I will take you step by step to show you how to make a 3 Bend Saddle in a length of EMT conduit. Using a good quality hand conduit bender from IDEAL will provide accurate and professional looking bends that electricians expect while on the job.
Hi folks it’s Ron with IDEAL.
In this video I will show you one way to make a three bend Saddle in a ½ inch EMT conduit using a hand conduit bender from IDEAL.
The 3 bend saddle is similar to an offset bend, but this case the same plane is resumed. It is used most often when a pipe is encountered It actually is three bends in the length of conduit that will allow the conduit to go over the obstruction and continue along the path. Most common is a 45° center bend and two 22 ½° outer of bends, but you can use a 60° center bend and two 30° bends. You will use the same calculations for either set of angles and need to make three marks on the conduit to make these bends.
For this demonstration I will use our catalog number 74 - 026 Ductile iron head bender from IDEAL. The ductile iron head benders are typically preferred by the professionals as they will last longer than aluminum bender heads which are lighter weight but less durable.
I’m working with a length of conduit that is 60 inches long and because of the bends we will make to create the saddle bend the overall length of the conduit will shrink by 3/16” for every 1 inch of the height of the obstruction. In this case say the obstruction is this 2” PVC pipe which has an outside diameter of 2 3/8”. I will create a 3 inch saddle bend to go over this pipe with a little bit of clearance. Using a 45° bend for the center bend and two 22 ½° for the outer bends. Using the chart in the Ideal bender guide I can see for a 3 inch obstruction I need to move my center mark ahead by 9/16 of an inch. Which makes sense because 3 x 3/16” = 9/16” it becomes the shrink amount we will use to make the center mark. The chart also says the other two outer marks I need to make on either side of the center mark should be 7 ½ inches away from the center mark.
Step one is to measure the distance from the last coupling to the obstruction. In my example that is 30 inches.
Step two is to add the shrink amount from the table to the measured distance and make your first mark on the conduit at 30” + 9/16” or 30 9/16 inches. Contractors generally use a pencil to mark the conduit so it can be erased later. In my example I will use a permanent marker and mark the conduit all the way around so the mark will not get lost in the conduit head when bending.
The other two marks will be made at 7 ½” on either side of the center mark and again mark the conduit all the way around.
Saddle bends are done in the air not on the ground. Simply stand the bender with the handle pointing down and bender head closer to you.
Step three is to align the center mark on the conduit with the rim notch on the bender head. Then bend your knees and lower your center of gravity, set 1 foot next to the bottom of the bender handle near the ground to hold it in place and then tuck the conduit under your arm and bend the conduit to 45° using steady pressure to prevent any wrinkles or kinks. The bottom of the conduit will be lined up with the 45° mark on the bender head.
Step four is to slide the conduit down to the outside mark that is closest to you. Lineup this outside mark with the arrow on the bender head. Keep in mind you want to keep everything you have already bent on the other side of the bender head away from you. For these two outer bends the hook of the bender is pointing at the center bend of the saddle. Then rotate the conduit by 180° and using the handle of the bender lineup or align the first bend with this 2nd bend. Any time you’ve got two or more bends in a pipe, there’s the potential for what electricians call a dog-leg if the bends aren’t aligned. This creates a problem in the wall and doesn’t make for a professional looking bend.
Then using firm pressure again bend the conduit two 22 ½° again the bottom of the pipe will be even with the 22 ½° mark on the bender head.

I am a commercial electrician with about 14 years experience and I am embarrassed to say that the three point saddle has haunted me despite the fact that I can bend pipe with the greatest of ease. After watching this video I know they will haunt me no longer. Thank you so much for the great video. You rock !
Hey man I owe you for the comment I certainly don't bend conduit everyday but have taught conduit bending on and off for a long time. The real trick is just practice I like to say it is like your golf game if you play a lot of golf you will be good. Same with conduit bending. Have fun Ron
I wish this video showed the math behind the bends not just opening the book because in the field you may not have the book or service to look it up
@@michaelridlon9247 I take notes from this man’s videos. You gotta memorize
It had been so long since I bent a saddle, since I do mostly residential, that I forgot. You brought me right back up to speed on the first try. Thanks for all you do!
Matt I am the same way! If you don't bend conduit much easy to forget...Ron
Ron, thank you for posting this video. You merit a tip of the hat for this clear, helpful explanation. This video directly addresses an issue I have with an obstructive water pipe. My conduit bender happens to be an Ideal, making it that much easier for me to follow along.
Hi Jim nice to hear you could use the info. Ron
Thank you! We've got a 3 point bend to match tomorrow in our conduit run. It was intimidating to think about today but exciting to try and accomplish now that I have a better idea of what to do. I appreciate how you showed each step on the screen and explained and demonstrated them well!
You got this!Hey Donald hope it helps Ron
@@RonKipperDatacomm1 it worked and looked great! I had to use the handle of a second bender to cheat the last 22 into place on the short end. The other guys were doing the push through method I think.. but something about those seemed a little off, maybe they were using the wrong starting points.. looking into that method next..
Just takes practice! Good luck with it Ron
Thanks for the help!! You explain it really good and clear. Thanks again!!
Thanks Moe Joe!
Best tutorial on RUclips
Thanks appreciate the comment Ron
Get video I made three bends this week at work used your video very clear and instructions were also on the mark
OK great! Ron
Wow you simplify what’s been hard for me. New subscriber my friend! Thanks so much
Done have fun Ron
great presentation please keep them coming.
Thanks man those seem to be getting old appreciate you watching!
Ron
Best video ever made.
Amazing tool and skill demonstration.
Thanks!
Hello and thank you! Ron
Been out of electrical for 8 months this helped alot
I know what you mean bending conduit takes practice and if you are like me I do not do it everyday. Ron
Very clear and precise explanation
Hi John appreciate the comment have fun out there Ron
great explanation ron! good job
+Leo Lopez Thanks Leo! Good to have you out there. Ron
Thx
I done perfect on first attempt by your guidelines
You the man Johny! Thanks for the feedback Ron
Thank you so much! Ron , finally learn how to do the 3 point saddle .Rate=5 Starts.
Good to hear from you! Ron
👌
No wasted words ,selling benders yes,on point xnlt video...
Thank you Dave I try not to be boring........Ron
Best video I could find thanks buddy !
Thanks J I don't know about being the best video though..... Have fun Ron
Very helpful. Great instruction, thank you!!
Cool have fun Ron
Great video, very well done
Thank you! Ron
Very helpful video, thanks!
Hey thanks! Ron
Sir ,this it's a great 👍🏽 instructional video
Thx so much great help out on the field
Glad to help. Ron
Your videos are always so engaging :),
The subject for your vids are on point :),
This vids of yours had me glued to the screen:),
What camera do you use to film your episodes?,
What mike do use?
Scott nice of you to drop me a note you have the start of a nice channel. I have a Sony HDR-CX760 camera, Shure Wireless System and a ISOMax Microphone from Countryman Associates and some fairly cheap lighting. I digitally record the audio at the same time to a Zoom H4n audio recorder. They say the audio is just as important as the video if you want something with a clean look and sound. Then mix it back with the video and I can clean it up so it sounds pretty good. Hard to watch some of the old videos.............have a good night. Ron
Do a 4 saddle bend next ? You explain this very well 👏👏
On my list.. Ron
i would also like to see this.
Good job! Thanks for doing these I’m reviewing for a test I have with one of the Unified school districts in California
Thanks man appreciate you watching Ron
Thank you for a great video
Hey Paul thanks for being out there. Ron
Hi, I like your video. Thanks
Hey I appreciate you being out there! Ron
Teaching this to 1st years, thanks
Cool have fun with it Ron
love the video..very understandable..thanks
Thanks B!
Great video
Thanks! Appreciate you watching Ron
Great quality video, clear picture, clearly explain. Thanks a lot.
Thanks Ron
Saved my life thank you
Hi Jason doubt it saved your live but I appreciate the comment.
Ron
Thank you for this well made video. short, and to the point.
Hey Adam thanks for the comment. Your fried turkey look pretty good! Ron
Really fantactic.. Everything is clear... Turkey from İskenderun
Hello good to hear from you! Use the info well Ron
great job great video and you could possibly add that you are starting your Bend with a hook away from you for your first Bend and shrinkage will be taken up toward your body rather than saying the hook away only non shrinkage side of your 9/16 inch addition
kevin g thanks for the tip someday I will redo these and will add you tip . Ron
Gracias saludos desde Chile
You are welcome! Ron
Great video and audio especially. You have a natural 'radio' voice - you make that Isomax sound like an RE20! However, it sounded like there was some clipping - you might not need to run the mic so hot.
I was also a bit distracted by the zip cord on each side. I don't mean to nit-pick - just my honest comments. Thanks for the video.
Hey thanks for the audio tip! What I have learned about making videos is I don't know much about it! Always something to improve........I would love to have a dedicated space to shook these but that is not happening anytime soon so my shop is my best space. Appreciate the comments Ron
solid explanation
Thank you sir!Ron
great video.. thanks
Glad to help! Ron
Good teacher
Hi Elmer appreciate it! Ron
Ron, you should give away a ideal bender for Christmas... :) great video ...
+spyderx92 Are you in need of one. I have an older aluminum head bender I can part with if it will help you. Send me an address to my ron.kipper@idealindustries.com email and I'll hook you up. Merry Christmas!
Ron kinda looks like Santa..
Ron Kipper Datacomm,
Wow, what a kind gesture. :)
you're the best!
Hey man thanks for the comment I need to go tell my wife.........
Hi Ron, Thanks for the awesome learning videos. I have a #74002 will it make any difference? How do ideal benders differ?
That bender head is for 3/4" EMT conduit and the bender heads really don't differ other than the size of conduit they are designed for. Hope that helps Ron
Using a steel bender head is fine for 1/2" and even 3/4"
However, if you're using a steel 1" or 1 1/4" all day long, the aluminum head is more cost efficient.
I can go much faster with a lighter head.
I am a fit 200LB guy.
I like this video, very educative.
Good job i like it
Thanks Ron
Hey Ron , I have a 1/2 ' bender at home and am practicing my bends so I can work back in the commercial industry. I did a couple 3 bend saddles and followed your instructions , everything was good but I found I did not have a smooth 3 bend saddle the piece of pipe ended up with a big A form, I think I know why but not sure how to correct it. Could you give me some advice. Thank you.
D JA good to hear from you. Are you using the right size bender for the conduit? Not sure why you got a bad bend.Ron
Good vid. Finally good to see someone getting up all the way on the pipe when making bends in the air
Thanks for the feedback and yes it helps to work closer to the bender head. Ron
desde Chile, Gracias .
Hey glad to help thanks for being out there. Ron
very nice
Thanks! Ron
Can you bend IMC this way? I find that it is more difficult to bend in the air (I'm not a big guy).
Nicholas yes you can bend IMC with the benders and your right it just takes a little more effort. Ron
So it's called a Dog leg huh? You should see this dog leg I just made here.... :))
Thanks for the upload, easy to forget this stuff when you don't just do EMT everyday.
I agree bending conduit is something that is hard to do if you don't do it every day. kind of like your golf game! Ron
On your first bend, what side of your conduit were you holding? Were you holding the 30-inch side of the conduit? In other words was your hook of your conduit facing away from your 30-inch bend or toward your 30in bend?
Kevin yes I bent the center bend first holding the 30" side of the conduit. Basical anytime you are making multiple bends in a conduit the last bend is always facing away from you on the other side of the bender head. Hope that helps Ron
Hey great video , any tips for a 4 bend saddle 1/2 " emt. Thanks
+A Garcia The 4 bend saddle is just two offset bends in reverse. That should be another video.........Thanks for watching Ron
Make two offsets
Thank you
Use it well! Ron
can you do one for back to back 90 without cutting to length? great vid thanks!
+Heman Bowen Hello good to hear from you. I do have a video on back to back bends. ruclips.net/video/rX0HIvKWKqs/видео.html&feature=player_detailpage&list=PLw8qsvCN6q_0WYifgt9fX2KHEeck8aJJDThanks for watching. Ron
Thanks! I found it! Great vid too!
is the shrinkage the same across all sizes of conduits in a 3 and 4 saddle bend?
Yes the shrink amount does not change with the size of the conduit but does with the heihjt of obstruction. Good luck Ron
Nice video. Is there anyway to recover a bend that was bent too far?
Use the hollow handle to and slip it over the conduit to try and "tweak" a bend a little but if it is too far off you have to bend a new piece. The idea is to try and not waste too much conduit on the job. Appreciate the comment. Ron
Ron Kipper Datacomm
Thanks you
Appreciate the comment have fun Ron
What are the warrant ideal had on the products now i have used Klien my whole career but the are starting to stray from the warranty and acting like they are to good
Hey Chris the warranty on the ductile iron benders is a lifetime warranty. On the aluminum benders it is 1 year. Hope that helped Ron
What’s the plan when the obstruction is so small that your bends are really close to eachother and you just end up unbending the previous angles when you do the other two
Zach are you talking under 1 inch? In that case just make the center bend and flex the conduit using clamps on either side to continue the run. Have fun Ron
Did I miss something?? How did you get the 7 1/2” measurement ?
Nevermind, missed the chart, I skipped ahead. Thank you for this, my partner owes me coffee now haha
OK
I have the aluminum bender, and besides the notch near the star, also has 2 more small notches, do you know what are those for
Yes they are for making the center bend of a 3 bend saddle. The notch in the middle is for a 45 degree center bend, the one closer to the hook is for a 30 degree and the one on the other side by the star is for a 60 degree center bend. Hope that helps Ron at ron.kipper@idealidustries.com
@Ron Kipper From IDEAL thank you very much
Glad to help Ron
Shouldn't the total shrink be 9/16 * 2 or 1 and 1/8th?
Nope 3/16 * 3 which is the height of the obstruction I was using. Thanks for watching I will be the first to say I am not perfect...........
yesss: In this video, the shrink is implicitly defined as the conduit length reduction per HALF of the conduit segment. Goniometrically, for one half of the segment, neglecting the bend radii (r = 0), and using d as the shrink, h as the obstruction height, and t as the angle theta in radians, it can be derived that d / h = 1/sin(t) - 1 / tan(t). Entering h = 1 and t = 22.5deg/180*pi yields 3.2/16, so roughly 3/16".
The star, notch, arrow is the best way to do 3 point saddles because your saddle will more often be away from the centre of your emt.
Cheyne thanks for your input always looking for a better way. Ron
Are those measurements use in sizes 3/4 trhu 1” 1/4 emt?
Walter I am not sure what you are asking . Ask again Ron
It makes no difference, whichever emt you use.
No idea if you’ll see this or not BUT I’m practicing my bends with a 1/2” bender and what do you do if one side of the pipe is going up a smidge
You mean the conduit is slightly bent before you are bending it? Ron
@@RonKipperDatacomm1 no I mean after you do all your bends, one side is bent up a bit and not Flat, is it cause I’ve over bent it?
Kat that is called a dog leg and is cuased by not lining up your second bend with the first one. Generally I line up the first bend with the second by sighting down the conduit and rotate the conduit until they line up. I am pretty sure I mention it in the video. Hope that helps Ron
Are they still sale the bender guide
Yes just download it from the website

Ron
How did you get 7 1/2” for the sides ?
Got it from the chart in our bender guide Hope that help Ron
Thanx
You are welcome! Ron
Why 7 1/2 inches on both sides from the center mark?
Hi Brent the 7 1/2 comes from the chart in the bender booklet for a 3 inch obstruction that you need to go over. I am sure there is a math reason for this but the distanve is given in the chart. Ron
Why is the shrink amount only 9/16, and not the sum of all three bends?
Nicholas the shrink amout is based on the height of the obstruction 3/16" per inch of obstruction hope that helps Ron
do u have a video solely on 4 pt saddle bends
Hey John thanks for the comment and the 4 bend saddle is on the list to do. I've been pretty busy with other projects but I'll get it done. Ron
Great, and again thanks, I will be looking forward to it.
If you plan out your run, then you'll never have to to use a saddle..3 point or 4 point ...even with remodels you can use existing j boxes for a run..😊
In a perfect world right? Have fun Ron
this is liiiit
hyave fun Ron
tanxxxx
When you were venting that 45 since you added strength you never said which way the Bender had needed to face on that
Hey man the bender hook should be facing the 45 degree bend when you make them have fun Ron
2:45 “buuughghghgh”
Yes kind of stumbled there a little bit.....Ron
اريد الفيديو مترجم للعربى
Not sure what you are saying. Ron
I want a video in Arabic thank you
I am from Egypt and my name is ayman . please enter the Arabic language for all videos
Sorry sir I am not sure how to do that. I have about 300 videos and do this just part time. Appreciate you being out there Ron
I need the handle of the bender to be straight, so I can measure my offsets off of it. As well as being large enough to fit over the conduit to tweak. Why not invent a more sophisticated hand bender, that you can get exact degrees, without any tweaking. Maybe use lasers in the bender, with a digital readout. Or maybe notches that a mechanical stop can slide on and lock on, you set the stop to the degree you want. It already has spring back factored in, and probably has to be minorly adjustable, or if you give every single degree as an option, we will just know 1 degree less. Get to the inventing, I need a better bender.
Hey John some of your suggestions have been tried but a lot of learning how to bend conduit is just practice. I just passed along your comment to the product folks lets see if they come up with anything new. Thanks Ron

Hello have fun Ron
What's the best way to bend a 3 point saddle?
Bend a 4 point saddle.
OK I will have to make a video! Ron
How did you only lose 9/16'' of your overall length?? You should be losing 1-1/8'' of overall length. You lost 9/16 already at the center point and your only have way through the bends...
Hi Brandon I show at the end of the video that I lost 9/16" overall. Ron
I see
OK Thanks Ron
I am from Egypt and I follow you. Suggest that if these videos are translated into Arabic, you will get very great support
Hello thanks for the tip I will ask IDEAL Ron
4" pipe... please.
Jose 4 inch pipe is too big to do by hand! You need bigger bender Ron
exactly. show us how to do them on the big benders then!
Sorry I don't have any of that equipment. Need to get the Greenlee guys to do the video! Ron
you should start using a level
The level in a bender is only good if you are on level ground to start. We do sell some very nice levels today I have a video up if you want to see them. Ron
In the future they will have robots who can do this kinda thing. They will name the robot Bender. The programmers will accidently code in poor gambler and obsessive drinker.
Kim I am sure you are correct have fun Ron
I dont like this video,he didnt show how he came up with the numbers for the spacings,if your gonna make informative video you should take your time to explain every detail to your viewers.
Sounds like you need to make a video..........have fun Ron
How come you fat guys only bend 1/2 EMT and then only bend in the air?
not bad
but teaching not ok
sorry sir
