- An Under Door Tool is one of the most capable and impactful items you can keep in your arsenal of entry equipment. Over the years, folk have proposed a series of modifications or variations to this tool and lots of those ideas have potential. I often recommend folk check out some of the videos that NotSoCivil Engineer put out at the very start of the pandemic in this playlist here...

... for those of you with a "standard" and unmodified Under Door Tool, where do you start in terms of increasing its functionality? This quick video has my suggestions. The first one is pretty obvious, the second one is helpful, and the third one is an absolute game-changer.
Enjoy! 👍😁👍

02:06 🏋 Enhancing Grip on Under Door Tool:
Using heat shrink on the head of the under door tool improves grip without leaving sticky residue, providing better control when pulling handles.
04:59 🔄 Upgrading Cord Management:
Replace traditional methods like zip ties with a retracto line for efficient cord management, ensuring it stays out of the way during field operations.
08:12 💨 Improved Gas Injection for Bypass Entries:
Introducing the Gen 3 Rex nozzle adapter, which allows attaching a straw for precise gas injection during under door tool usage, minimizing the risk of triggering alarms in secure spaces.
00:41 🚪 The under door tool is highly recommended but can be improved for better effectiveness. Adding heat shrink to the tool's head can enhance grip without leaving residue.
02:54 🧳 The cord of the under door tool often kinks; a retracto line attachment is suggested for smoother operation in the field.
06:48 🚨 Prevent triggering alerts: Using tools like a magnet switch or tripping sensors can help evade detection after using the under door tool in secured spaces.
08:12 💨 Utilizing R134a with a modified straw can deceive sensors post-under door tool use. The adaptable straw design aids in directing gas efficiently.
12:29 🛠 Upgraded under door tool enhancements, such as better grip, retractable line, and gas nozzle additions, can significantly enhance functionality and safety during covert entries.
I've used the gas trick in a pinch when a customer's access control system faulted out and wouldn't read anything anymore. Physical security guy was talking about having to cut doors and such. He was decidedly unimpressed with my trick until I got us all the way to the server room (which had its own, independent access control) to shut the main one down. The client was not impressed with the security contractor in turn about.
Self fusing silicone tape is also pretty grippy. Useful for putting on your mini flashlights so you can hold them in your mouth without metal on your teeth.
My first thought was something like plastidip?
I wonder how that would end up working?
Seems simple painter's tape would be a cheaper, more viable option. Literally designed not to leave residue too. Another option comes to mind, but I'll keep that on the back burner until I can test it out.
@@runeberg6514 For a fact, plastidip will wear off after a while... So you'd need repeated applications if you want to go this way...
@@zac08unlike heat shrink?
Latex bandage wraps would work as well.
I'm not a pen tester or a criminal but it's still fun watching you do this stuff!
Im surprised you didn't mention the not so civil engineer's tip with the hook for smoother door handles. Never thought about shrink wrap on the top. I have a bunch. I may have to add that to mine.
Great ideas as always. Hope everyone is taking care
I linked to him in the doobly-doo when I posted
@@DeviantOllam ah. Excellent. I didn't see that. Haha
The long straw and the under door tool are used as a firm extension for the long sprays…
Starting to think of Deviant as the arts and craft of covert entry. 😆
"latex" tubing gives more grip than heatshrink - sold for aquarium air tubes, Make sure it's latex or sticky silicone not hard plastic tubing, secure in place with a drop of glue. Might need some lube to get around the corners when installing it.
Try soapy water for lube down the tube. Once dry it shouldn’t slip. It seems to work when applying window tint.
@@itwasrightthereAnother lube for getting rubber parts on is hand sanitizer or another alcohol product. It quickly evaporates and leaves no residue.
#3 blew me away. Missing notsocivilengineer and his creative innovations and shenanigans! Hope he's having fun with CI and LPL!😁
Never has a video title like that actually been true. I was indeed, literally blown away
I think it's funny how many bicycle tools can be used for pen testing :D
And they do not require much to be 'just bike tools' unlike a bat in a trunk needing a mitt and ball. ;)
those things for the co2 cartridge can be bought in bike shops for emergency tire refil .
As always awesome. Thanks to you and everyone in the community.
You sir are a modern Krieger. Well done!
Nothing beats a good old under-door-tool mod! 8)
I never cease to be amazed by your hacks!
Shirnk tube is also good for rifle cleaning rods.
Polyolefin ftw
That's a cool use for the Kiwi pulleys! I immediately recognized them because I use them for their intended use: Hoisting my VR cable up and away smile 😄
Furry
Love it! I actually put together a knock down version threading together and bending rifle cleaning rods, and Red Team's retractable line.
Had good results with a Wacky Wallwalker/ sticky octopus. Soft & grippy with minimal residue and available in all good toy stores.
Awesome mods! We have used this tool a few times on fire calls.
Nice. Those are some great ideas.
Thats nice idea.. im not a pen tester, just an aaa auto locksmith... great info 👍
Nice changes. Have a good Tday and remember, dispose of fine amber liquids after dinner.
Awesome! Loving the constant innovation. Shame shipping compressed gas seems to be problematic
What a tool...indeed
nice wouldn't have thought about the retractor mod.
Soo brilliant. Greetings from Belgium's red team.
As soon as I saw the blaster come on the screen and noted it's shape, I knew what you were up to 😂
Great idea!
Awesome mods
Man, you have to improve on everything. I love it. Keep it up..
realy cool and without any zipzap around just the input about the mods ;)
Thanks Deev! I am a big fan of REX in the lock itself, rather that the motion sensors. However, now I need to go back and install locking thresholds and weatherstripping in the most secure locations to prevent the under and over the door attacks (since the UDT defeats my solution in one easy step). Remember the original interlocking weatherstrip that was routed into the door and frame made from copper; probably the best to prevent attacks but sadly obsolete. Might even need to think about mechanical door position switches too with shim deflectors. Its a great cat and mouse game we play....
You could also look into automatic door bottoms!
Deviant is such a badass.
Already using mod 1 and 2. Mod 3 is a potential game changer.
Oh, good vid. The not so civil, your old contemporary mod-ed this. I like his mod of the tip of the UDT that he Dremel's a flat hook on. I come across Single Crash Bar doors all the time and they can only be opened with that mod, you jam the tip into the back side of the crash bar and then pull your string to depress the crash bar, though depending on the resistance of the bar, it might not always work. It's one of the few scenarios you would ever have to pick a door, and that's only if there isn't some way into that area that ISN'T a single crash door, but they're usually impossibly fitted so even putting a corkscrew through the side to depress the side latch usually isn't feasible either. Plus you have to use a wedge if you're using a corkscrew which is a pain. Anywho, thanks for the vid- pretty cool. You should do a vid series on attacking Cores, so many ways you can get a core out of a door, go somewhere discrete which most buildings will have, decode, repin, replace, go get key cut or file your own. Nothing like having a key for a door, plus you'll get Control info most of the time which can produce insane results. My complex has different Op's for each buildings Mech- but the Co is the same for all of them, haha. Having the Co is like having a Grand Master key. Anyways, thanks.
double thumbs up!! 😀
I keep one version of mine in a shotgun pouch it fits perfect and I have a version that works on specific knob sets.
another idea to make it a bit more grippy than the heat shrink... You know those 1/2in wide rubber bands a lot of grocery stores use to bundle broccoli heads? Take one, cut it so it's a strip, attach to the tool with a couple drops of glue.
Also a neat idea
nice
I like it all
Amazing! You are Q from James Bond.
Love ya Dev!
Love you right back 😉👍
You know this reminds me of the claw on a stick for picking up things off of shelfs or the ground. Why not use bicycle break cables they come in plastic lined tubes and you use metal elbows to shape it pull the brake like on a bike retract and grip the handle lock it into place.
Deviant, sir. In your videos and conference talks you often show how to better secure a door to avoid under door tools, I was wondering if you've heard of this one: When a door has an automatic door closer, like in a hotel room or office, and you are worried of someone trying to enter while you are there, you can take a small towel or even shoe laces and tie them around the scissor portion of the door closer. I've never had the chance to confirm this, but it seems that this would render the door effectively un-openable?

You think you’re getting younger? You should see me😂Happy Thanksgiving Brother!
Man, the first two were great and then the third one literally shot me in the face and I died like a dog in the street
😂
Am i correct in guessing adding the heat shrink during manufacturing would close to double the manufacturing cost because it would add a manual step to an otherwise completely automated process?
Yeah, touch time would go up so much
I love it.
I'm guilty of having one in my bag but still haven't managed the EDC model that works more than once or twice.
The closest I've come was a small handle on a piece of fiberglass conduit snake (as in what you'd use to pull wire or cable) but keeping it coiled smaller than a BIG cargo pocket had glass fibers popping off everywhere.
If anyone has ideas, I'm all ears.
Shape memory alloy?
Not sure what the product would be in the US, but in Australia, they have sub-flooring with a plastic (probably HDPE) tongue to link it together, commonly called yellow-tongue, it's a super common cheap fish-tape that gets used by AV, security and network installers all over. Should be fine to only be 2.4m long for an under door tool.
@@mycosys I like the idea. I'll look at options within my budget but I don't think it'll be stiff enough to deliver the pull cord and then there's the need for heating it, in a non-permissive environment and with time constraints.
But I appreciate the "your box is a constraint of your own making" kind of thinking!
@@KarltheKrazyone fish-tape is a common term here in the South East US too.
It's tough to convey to this broad audience when the same tool has so many nicknames, right?
I'll look for an all plastic type to try.
I'm curious, do you mean that the tongue and groove flooring reserves a space for low-voltage runs? That's brilliant!
The heating you can do with a battery (its just a wire, thats how they do memory alloy muscle), and if you have enough it can be incredibly stiff @@matthewellisor5835 , its normally titanium alloy after all.
The main issues would be the cost and difficulty to manufacture in the first place
I'm almost disappointed you didn't say "pretty good enough" about your figure 8 knot.
Holy cow... As soon as I heard REX sensor I said out loud "What? No way..."
Can heat shrink the tube on too.
As an only-an-armchair-redteamer, this has me wondering about attaching the end of an endoscope to the underdoor tool as well. I'm guessing most of the time that's not needed because there's nothing surprising about the door handle so it's easy enough to open it without having a good look at what you're doing?
@@ts757arse : Hah, yes, I was just thinking of the construction/mechanic-grade endoscope camera, not the full-on medical endoscope tool. Though indeed the latter would be an interesting tool for the purpose!
@@ts757arse For a small cheap endoscope look for an ear one. Mine has its own screen attached by USB to the endoscope and though its meant for close up it will show farther away as well with a decent picture. The camera for it is the size of a thick phone
How about making the under door tool out of hollow tubing with the canister adapter apparatus integrated into the handle end, and having the spray nozzle end somewhere up before the 90 degree end that grabs the door handle? “I’m the visionary, you’re the nuts and bolts” - Bart Simpson
I am not that big into security (especially NA) but wouldn't triggering the REX sensor open the door anyway? why would it be useful to have it on the UDT other than directing the tube if it is not accessible from the outside?
REX sensors do not always trigger the electric lock to actuate. It all depends on how the access control system is programmed to process the REX event. Often times the REX is only used for the access control system to identify that someone is trying to leave (on their own), vs letting them out.
In higher security facilities REX sensors can be used to monitor the door, but not open it, so there may be a REX that monitors for movement, but the door is not connected to it; say if it is just a plain old door that does not require a lock from one way. If the door opens but the REX does not trigger an event, it would raise an alarm. This gets more complicated in the situation that Dev mentioned where there is an electromagnet and a REX sensor both monitoring, but not protecting, the door. If both are not triggered at approximately the same time they will alert security.
The other replies here that you are seeing all have it correct pretty much... Triggering a REX sensor sometimes completely unlocks the door (like in cases of electronic mag locks) but other times the REX sensor is merely used for monitoring and the door itself is unlocked with the turn of a handle (typically in cases where the axis control system relies on an electronic strike plate)
@@DeviantOllam @btw111 @David-yz2ks thank you guys. makes sense now
I tried to order this tool a few months ago but it was out of stock. I no longer remember the website. Any help on that? Thanks and keep the videos coming!
That awkward moment when you don't realise someone is in the room and they go to investigate the odd metal thing that just came under the door. Just as they realise it is turning the handle they get blasted in the face with cold air. Their flailing around while screaming, "My eyes!" will really ensure the sensor is tripped.
how long is the cord on that retractable cable key ring thing?
I always wondered if one of those bore scope cameras would be of any use.
Or slide your cell part way under the door. If this tool can get in a phine usual can too.
Now you have to remake your nozzle with a 45° on it so it can be more in-line with the shaft of the underdoor tool coming off the handle.
With r134 a thing. why not desgin a system that would look similar to what's used on old school wd-40 cans with the red straw? or that design patented or something?
USB phone borescope gaffed to the side of the vertical part of the UDT. You get to record your failures....
That's an amazing upgrade! And I must admit, I've never given any sensors much thought.
Incidentally, you're asking for an address on your give-away form. I've moved, how do I update my address? Or do you send an email first anyway, should I win?
Yeah you can reply to any future "you've won" email
>Number Three Will Literally Blow You Away
Let me guess: My personal favorite: C4? ;)
Hey Deev. why are you not gaffing one of those mobile phone borescope cameras to the under door tool so you can see what youre doing?
I'm 110% sure you have one, and i imagine it occurred to you?
Very nice
I was just wondering about this... I feel like hearing from multiple folks on how they throw there UDT or if they have any unorthodox style with it.. lol they need a once every other year under ground but filmed door pop Olympics ... you run that after battle bots and maybe television could make a comeback lmfao
why not use a tube rubber band to make the end more grippy ? like the ones on slingshots ?
I'm a little confused with the gas canister. I don't understand why you would use the under door tool if you're already tripping the rex sensor. I thought those rex sensors always unlock the door too. Is that no tthe case?
Unlock and unlatch are two different things. The door needs to be unlocked from the inside, or the under door tool wouldn't be able to turn the handle to open it -- but you still need to turn the handle to unlatch it. And presumably it's still locked from the outside, so you have to turn the inside handle.
@@BrooksMoses But he's asking why the gas canister? Makes no sense because the handle has to open and allow egress to meet fire code.
@@richardb8104 nah, I got that. Just in case the place has a security panel that would show an open door, triggering the rex sensor would make it look like someone was leaving rather than entering.
I think I had assumed that triggering the rex sensor would unlock the door from both sides. I have only ever seen the electronic door latches that trigger the stopper in the frame, so you could open the door from either side, but I'm not in the industry, I only take a passing interest in these videos so it is entirely possible that there are systems that control the latching in the door rather than the stopper. 🤷♂
yeah I've encountered doors where tripping the rex sensor doesnt unlock the door from the other side, and using an under door tool alone will read as a forced entry, so you need to do both
It's the "Deviant Under Door Tool".
Is that a disembodied GG behind your right arm?
Hah, It looks like it, doesn't it? That's one of our key making machines that we designed.
@@DeviantOllam it certainly looks like some inspiration came from Cody ;)
What am i getting this suggestion for?😂
👍 für den Algorithmus
Wait. Why do you stick under the door under the lock instead of under opposite corner leaning diagonal over the lever according to instructions you get more leverage chief.
Never heard of them glad I did wish they did not exist.
Im so confused about whats going on here but maybe thats for the best.
it seems too low to trip the rex sensor with spraying at the handle level
Nice Peterson Vice Grips, but ya shoulda used some electrical tape to soften the jaws biting into the cord/rope!
is there a reason you don't mention the site?
It's because I don't want to sound like a guy who's turning his RUclips channel into just an advertising conduit. It makes me feel crass.
After number my mind was not blown in any way shape or form, my mind is still there. Don't know how you can do something to my mind from a phone screen.......?
5/32 air brake line works better
I still have my ghetto version I made from literal garbage that I used to retrieve a box of my things from an office space after I left the job and turned in the keys (which I shouldn't have that early but eh what's done is done)
/s I have no idea why TSA doesn't like seeing all this on scans. Much less the crate(s) of guns. #tiredjustthinkingaboutit
For me this is utterly useless information but it was very interesting nonetheless.
If number three isn't a dustbuster or c4 I'm unsubscribing for false advertising
crime spree !
Does anyone think this might be helping criminals?
Seems like this is a video for criminals that is passing as 'security' or 'pen' testing. The shady not mentioning the website seems like some gray area bullshit.
