Making Offset bends in electrical conduit is pretty easy. I will show you step by step how to make the Offset bend using an IDEAL Hand Conduit Bender.
In this video I will show you one way to make an Offset bend in a ½ inch EMT conduit using a hand conduit bender from IDEAL.
The offset bend is used when an obstruction requires a change in the conduit’s plane. It actually is two bends in the length of conduit that will allow the conduit to go over the obstruction and continue along the path. Before making an offset bend, you must choose the most appropriate angles for the offset. Keep in mind that shallow bends make for easier wire pulling and steeper bends will conserve space but harder to pull through. For small kicks of 1 to 2 inches that feed electrical outlet boxes a 10° offset is generally used. For obstructions between one and 6 inches 30° bends seem to work best and for obstructions that are in 8 inches or more 45° bends are recommended. However any of these angles can be used to create this offset.
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.
Since we’re bending angles in a length of conduit trigonometry comes into play and depending on the degree of the bends we are making a certain shrink amount and distance between bends will need to be calculated.
I’m working with a length of conduit that is 60 inches long and because of the two bends we will make to create the offset the overall length of the conduit will shrink by a certain amount which is dependent on the degree of bend we are using.
When using 22 ½ degree bends the shrink amount is 3/16” for every inch of obstruction to go over and the multiplier to determine the distance between bends is 2.5. For 30° bends the shrink amount is ¼ inch and the multiplier is 2.0 and for 45° bends the shrink amount is 3/8” and the multiplier is 1.4.
We make this easy by providing an offset bending guide on the handle of every Ideal bender.
Looking at the offset bending guide for a 4 inch offset using two 30° bends. The guide gives us a shrink amount of 1 inch and a distance between bends of 8 inches. That follows along with the shrink amount and multiplier given for a 30° bend with a 4” obstruction. 4 X ¼” = 1” and 2 X4”=8"
Step one is to measure the distance from the last coupling to the obstruction. In my example that is 36 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 36+1 or 37 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.
Step three is to make the second mark on the conduit at 37 - 8 inches or at 29 inches which is the distance between the two bends.
Offset 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 four is to align the mark at 37 inches with the arrow on the bender head. Using the graduated marks on the bender head bend the conduit to 30°, the bottom of the conduit will be lined up with the 30° mark on the bender head.
To do this 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 using a steady pressure to prevent any wrinkles or kinks.
Step five is to slide the conduit in the bender head and align the second mark at 29 inches with the arrow. Make sure to align the two bends before making the second bend. Carefully line up the first bend with the second bend or you’ll end up with a dog-leg. 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.
Use the handle on the bender to align the first bend with the second bend. Then using a similar technique bend the second 30° bend creating the 4 inch offset.
Using a tape measure we can check the accuracy of the bender and you can see the offset is 36 inches from the end of the conduit and the offset is 4”.

You were meant to be a teacher. I'm blown out my mind and I understood everything perfectly! lol
Hi Dannycan thanks I do appreciate you being out there. Have fun Ron
your lesson is much simpler then most I had seen so far
Hey Don the offset is not hard to do and a little practice goes a long way.
OMG. Its so refreshing when a professional shows you how to do it. Too many hacks on youtube. Thank you Ron!
Hey Randy I don't know about the pro side of what you said but I appreciate it. Hope these videos help the folks out there who are just learning about conduit bending. It takes lots of practice to get right have fun Ron
@@RonKipperDatacomm1 I'm an HVAC guy for 42 years. HVAC educator for 28 years. So much pure crap on RUclips in my trade. But your video was spot on. I'm doing my own conduit in my new shop. Thanks to you I can now make a box offset (in the air of course)! I'm still wasting a little pipe but I'm getting better...
Thank you sincerely
Very clear explanation!!! thank you
Diego use the info well have fun Ron
Thanks for all your help, easy to understand and very informative. Couldn't have done my project without your help. Keep up the good work!
Hi Brett appreciate the comment. Ron
I really appreciate the video, I'm new to the trade and I had no idea what that chart on my ideal benders was for. Thanks for your time.
You are not the first guy to say that! Thanks for the note Ron
You help me so much in my career, thanks for making this video.
Hey I really appreciate that! Ron
this the best ever learning resource from Ron. Immense help to any one. I bought two benders and they work a treat. very cool
Happy to be of service. Ron
Thank you for this, I will look for more of your videos.
Appreciate you watching Ron
thx I enioyed the lesson,I really desire to get the conduit bending down to the science
thanks for the sticker for my benders i also got my new boots for my benders got 6 they work great
OK leo thanks for watching Ron
if you make more videos, we would appreciate it.
Ramon I know I know...........need to make more video just can't find the time but hoping to change that.
Ron
great video ron
Thanks! Appreciate you being out there. Ron
this is video is the all best
Thanks for watching I need to make more of these videos. Ron
Good job brother
Thank you sir
for shallow offsets the thickness of a 2x4 (1-5/8"), I've found it is necessary to subtract an additional 2-1/2". Mark (B) would be at 26-1/2" in reference to this video.
OK Steve appreciate your input Ron
Good job i like it m teacher thanks
Use the info well Ron
I really struggle avoiding dog legs, especially on short box offsets. Any tips to improve? Thanks.
Hi G Davis maybe slowing down and sight down the pipe before the second bend. I would not think doglegs would be a problem with the box offset, Have fun Ron
You said the first bend should line up with the 37” mark. Didn’t you mean the 29” mark,or did you turn the conduit around? It appears as though you bent the first mark from the end which would have been the 29”, correct?
Yes the first bend is made at 37" then slide the conduit in the bender head and rotate it 180 degrees the line up the arrow with the 29" mark and make the second bend. Watch the whole video and I show making that second bend. Have fun Ron
Are you measuring from the coupling to where the obstruction STARTS or to its center?
Hey Matt typically we measure from the last coupling to the where the obstruction starts for offset bends. Hope that helps Ron
Ron Kipper Datacomm Absolutely. Thanks
Is the multiplier any different for 3/4" conduit? What about the shrink?
jt5747 it is the same Ron
I would like a replacement decal for my handle, but sadly I cant get one.
Hey John I can help with that send me your address and I will get one sent to you Ron at ron.kipper@idealindustries.com
You Good job
Ali thanks Ron
how do i get the stickers to replace on my ideal benders we have 9 of them bender charts are all scratched out
leo send me your address and I will send you some. How many do you need? Ron at ron.kippder@idealindustries.com
7306 iturbide st. Weslaco Texas 78599. need 6 will be getting2 new 1/2 benders Monday looking to try the boots will see if they have in stock to buy on Monday great class on pipe bending thats my to go for reference for my apprintice kitchenworkshvacr@gmail.com
Leo I just order 10 of the stickers for you. You should see them next week at the latest let me know if you don't get them. Ron
that was a fast reply that because i sent email after email to the ideal manufacturer never got a response back in a honesty i sent 6 email will be getting my new benders today also an ideal wire nut driver
Sorry for the trouble you should see them this week. If you ever need help contact me or our 800-435-0705 customer service number. Ron
Great video where can I get the bender sticker
Marizel call IDEAL customer service 800-435-0705 and ask for a P-099 stcker. They should send one out to you. Hope that helps Ron
Ron, which U.S. State are you in?
Hi Francis I live in Kansas Ron
How do you open the freezer?
Hi Sky Dan nothing but food in the freezer! Ron
Every time i do an offset bend with the correct multiplier, my offset always exceed the measurement I got.. for example if I need a 5” bend And use a 30 degree bend I’ll multiple that by 2 so I’ll get 10” between bends. When I finally do the bend I’ll get maybe 8 or more inches instead of 5.. it’s so annoying
Antonio sounds like you just need a little more practice! Have fun Ron
Seems like you might be bending beyond the 30 degree mark so you are getting a larger offset.
Lastimosamente no ahí una explicación así en español 😢
