I'm a JW with almost 20 yrs experience. I can recall exactly once, about ten years ago, I actually used this. I wanted to use it recently, but couldn't remember it for anything. Thank you for the refresher.
I was sent to do 6 pipes into a pull box all parallel offsets(17.75” offset with 5.25” kick). I have never done parallel offsets before. I went into the bathroom and watched this video and taught myself how to do it. 2nd year apprentice. Thank you very much for the video.
Thanks a lot. I was running 2 sets of 2" EMT today side by side, and I did both of my offsets the same and I had to make my gap before and after my offsets way bigger than I wanted to in order for my pipes to not be so damn close during the offset. I was curious to why and knew there was a better way, I will use this in the future all the time!
Hi Walter, from one tutorial maker to another, I want to encourage you. It is obvious that you care and are attentive to detail. Every video could always be better, but with enthusiasm and a solid plan (vision), you've made a video that can help many, many electricians to become more skilled in the trade. Well done man.
Thanks Matthew! I really appreciate the comment. We are trying to create tutorials that are helpful and hopefully enjoyable to watch and learn. It means a lot to get comments from another TH-cam creator. Keep up the good work!
Man this is the video I've been looking for!!! Please make more videos about conduit with the tips and tricks, matching couplings, matching couplings on 90's, rolling offsets, 3 point saddles, 4 point saddles. Sorry to ramble on I just like learning about the art of conduit bending and this is the only video I've found someone using an electric bender. Awesome video!!!
Thanks, Walter, for a very clear and concise description of this process. A note for all of you aspiring technicians out there-learn your math, especially trigonometry (I know, it’s a more advanced course!). You will be able to use all the shortcuts while having an appreciation of the math behind it and not be totally confused.
Thanks for your comment Terry! Right angle trigonometry is very helpful for understanding so many different aspects of electrical theory, such as reactance. Thanks again!
great video. in the trade for 20+ years. never had a real opportunity to work with rigid pipe. that's where the true masters work. a lot of younger guys don't want to learn and a lot of contractors don't want to pay the time it takes to do good looking work.
Well explained as a pre-apprentice this helped a lot! We did a parallel offset today but my journey did a pretty shitty job. He didnt use tangents, shrinks and angles. I think he just wanted to finish the job. Didnt really learn anything from him.
I'm curious what kind of techniques he used. There is an old timer method for eyeballing offsets with minimal measuring, but it doesn't work well for paralleling. Keep trying to learn and hopefully you'll find someone in the field who likes to teach.
Please make more of these videos! Do a 3 point saddle and a 4 point saddle bend. Its helpful to see the process and which way to flip the pipe in the electric bender.
I was using this for some parallel Kick 90s and the formula was not working for me. Figured out that since it’s just a kick and not a full offset you use the tan for the full degree times your center to center distance. So for my 30° kick I used the tan of 30° instead of 15° like I would for parallel offsets and it all worked flawlessly. Great video.
In the field no one uses this book, maybe in the shop but dog legs are the norm on 1” and below. There’s offset hand benders for box terminations, that tool saved me so much time as an apprentice. If you’re off on measuring the run we just used our hacksaws.
Like I’ve seen others say, you don’t use it you lose it. I recall a man who grew up with Hebrew as his mother tongue and learned Greek and because he was over many years without speaking or reading his mother language, he had forgotten it. I think this is true for whatever you may think you know!
great job at explaining this!! thank you. It has taking a great effort for me to take on this challenge out in the field without this information on hand. The way you have explained it, it's really black and white.
as a first year about to do his first performance evaluation this was extremely helpful, the only thing I am not confident about is parallel offsets so this helped a bunch
Really great video . Now if you are bending conduit that’s in a wall you probably don’t need this but if it’s exposed this video will make an apprentice look like a pro Thank you
Hey man I appreciate the video, I just started my third year of an apprenticeship and was never shown this before. Im sure I'll be able to make good use of the info.
I’ve been an apprentice for about four months. I started bending pipe today and did pretty well. Thank you for giving me the knowledge and formula to improve. If you can do a video on kicks and matching kicks would be awesome
Just found this great video really explaining and more importantly showing how simple these bends can be! Thank you & please keep making these great video’s👍🏻
Having worked for electrical contractors for almost forty years, and ran enough conduit to cross the State of Pennsylvania, I can honestly tell you if you used these complicated methods and took this much time it would look pretty, but they would run you off! What they want is clean, simple bends through which wire pulls easily, can be fabricated quickly and installed without a lot of fuss.There are much simpler methods which are more practical.
Very interesting! Tangent of half theta is the same formula as for the shrinkage multiplier (to multiply by the height of the obstacle and compensate for the shortening of the pipe due to bending). Thanks for explaining this in a non-technical way. I like how you used Uglies because I think it will be less worrisome to newbies than trying to teach them trigonometry.
I did this on 4” rigid I was bending. You have to do this or your bends will hit (if you run tight center to center spacing) and you won’t be able to spin on your next bend. If you use this formula, Not only will your diagonal spacing be the same to your parallel spacing and look great, you will be able spin on your additional pipes.
I was trained to use the shrink value for the angle I’m bending and multiply it by the center to center distance for parallel offsets. It works well. Just in case you don’t have an ugly book.
Okay, guys… Not to rip on the instructor as his experience is truly impressive, and rewarding to learn from. However… To find the multiplier of *any* angle isn’t as simple as “just checking in the Ugly’s book for what the value should be for the angle of the bend” because one might have an angle that’s not listed that they might still need to find. To find the multiplier of *absolutely ANY angle*, you use the cosecant of the angle you’re working with, or csc (theta), which equals the fraction of… (1/[sin theta]) …which will give you the multiplier value of *any angle*. However, there’s still one more step to achieving this value that is ALWAYS helpful. If you know that you have to bend at a certain angle and can’t find the value of sine as the denominator, you can convert the angle to radians by… multiplying [angle] * (pi radians/180), then reduce the fraction. Using sin of this *also* gives you what the multiplier is, with the numerator being 1 - a key component of the unit circle.
Great video, however I have a suggestion. Use a digital protractor on the long side of the pipe , zero it, than after your first bend test the bent end for 30 degrees. Also note the spring back and write it down for the next guy. For example you might have to bend a 33 degree bend for a perfect 30. Thank you for your video.
Very nice job. Thx for sharing. Would you do a presentation with multiple difficult bend angle with the pipe pre cut exact length and compensate for all gain and loss.
At 10:27 in the video, you measure the distance of the pipes. Are you measuring the gap you wish to maintain from the center of the pipe that has the tape stretched over the top? Or are you measuring from the edge of that pipe to the edge of the pipe you already bent?
When running a rack with different size conduit, should you bend them all on the shoe from the biggest size conduit in that rack because of bend radius difference or doesn’t matter ?
If you are running rigid or IMC conduit it is a good practice to use the largest conduit shoes for all your parallel runs. You can’t really do that with EMT though.
Thanks a million for your wonderful training videos. Also I would be thankful if you could let me know if we should use the tangent of half angel of the prior conduit when required to make more consecutive parallel conduits or just the tangent of the half angle of the very first conduit. Thanks again!
I'm confused, aren't you supposed to add some length for shrinkage to ensure the clearance to overcome the obstruction? Did you accomplish your 12" height to clear the 12" obstruction? Enjoyed the video very much. Thank you.
Thanks for the video but let's save some time 1/2 tangent of your degree x gap of pipe. Add or subtract from your 1st mark depending on if it's the shortest or longest your starting with. Also this should work the same for kicks
First video I’ve found explaining this perfectly. Great job
4th year apprentice here , thanks for the smooth video 👌
Glad the video was helpful, and thanks for commenting.

That's why apprentices are on the toilet so long😂
So sad no ones being taught@@400080vikkash

Excellent video. Not many people are doing these sort of videos for the electrical industry. Keep it up!
thanks for the comment TRUTH!
Yes! Please more pipe bending videos. This was very well explained. Thank you.🙏

Push through method bending on centers. Multiplier 3
Great videos sir,, please keep putting content out! The industry needs it
Very helpful. As a freaking union 3rd year apprentice who has yet to do this in the field, this was very helpful to know

Clear. Concise. Perfect instructional style for me. Thanks!
This guy rocks.
Nice idea with the strap and strut for the no dog level. If i forget my no dog on the job one day im gonna remember this. Thanks.
Thank you for this video! Makes way more sense than when my teacher went over it.
Great job, continue the great work
Thank you for the comment. I appreciate the feedback.
I very been ibew electrician, I don't know if you union or not. But your very knowledgeable. If not, you might want
Want to join ibew, we could use a great hand like yourself
Amazing video access to power is golden
Great job! Simple, concise, clear explanation. Look forward to seeing more of your videos.
Really great video . Now if you are bending conduit that’s in a wall you probably don’t need this but if it’s exposed this video will make an apprentice look like a pro
Thank you
Please make more conduit bending videos. They are extremely helpful
Thank you for the time and effort to make and post this video. The offset calc for parallel runs using the tangent trig function is what I needed.
You’re welcome! Thanks for commenting.
You are going to be my teacher.
great video by a great teacher
This guy explains everything so well
Hey man I appreciate the video, I just started my third year of an apprenticeship and was never shown this before. Im sure I'll be able to make good use of the info.
I have problem with a paraller offset but now I start to understand with this video
best video so far
I needed this ....thanks a million
Wow this is great for our new guys learning. Cant wait to see what's next. Very useful.
Thanks Andy. Glad the video is helpful.
Perfect please more parallel bends. With other angles.
Very nice bender, you make it look so easy!
Thank you for this great explanation. Really easy to understand. 👍👍
By far best explanation
Excelente , good for everybody , so we are on the same pague AND use the information .
Thanks.
Never knew the tangent of half the angle method that’s pretty cool. way easier than the way I was taught haha thanks
Excellent tutorial keep up the great Work
Good job with these videos I used to work with you guys back in the early 2000s when Pon came over from Walter Electric
perfect simple explanation thank you
I’ve been an apprentice for about four months. I started bending pipe today and did pretty well. Thank you for giving me the knowledge and formula to improve. If you can do a video on kicks and matching kicks would be awesome
Great video always wondered how that was calculated.
teaching this to 1st years thanks
Thanks for this video. You did a great job in explaining it.
thank you, I needed this lesson
Great video!!! Def keepem coming
Just found this great video really explaining and more importantly showing how simple these bends can be! Thank you & please keep making these great video’s👍🏻
Joe V Thanks for the great comment. More videos on the way

Great cristal clear content
Great job, very helpful video
Make more! cool video really informative
That’s a cool idea strapping a deep unistrut to put the level on top 😊
Seems like it was fiberglass too
hell yeah i like this video very helpful, thanks for teaching!

If you use this formula, Not only will your diagonal spacing be the same to your parallel spacing and look great, you will be able spin on your additional pipes.
Great video. Please make more videos using the hand bender also.
Thanks for the video. You got another subscriber.
I was trained to use the shrink value for the angle I’m bending and multiply it by the center to center distance for parallel offsets. It works well. Just in case you don’t have an ugly book.
Thanks, great refresher. Super helpful. Can you do one for matching center of bends with varying angles, too.
I like the explanation.
thank you. Learned a new trick today I appreciate it
Thank you so much for the info bro!! Really makes a difference for me.
Great video
I leaned something today :)

Hi, great job. Thanks
Can you please make a back to back 90, a 90 with an offset , your videos are very helpful!

Ali Ahmadlou the parallel conduits would have the same angles
profesor for conduit 4 " is the same procedures???? or there are other table???
you clip it helps a lot thank you so much
Hi thanks for sharing with us your knowledge and may God bless you for that. I am watching from haiti. Have you ever been to haiti?
Jude Belzy thank you for your comments. I am glad this is helping you. I have never been to Haiti. Maybe someday I will have the opportunity to visit.
Wow..nice sir.. .
Great job!
Brilliant.
Great video. Definitely subed
I'm confused, aren't you supposed to add some length for shrinkage to ensure the clearance to overcome the obstruction? Did you accomplish your 12" height to clear the 12" obstruction? Enjoyed the video very much. Thank you.
Hi
I'm from the UK, can you tell me the name of the protractor you are using to set the angles on your pipe work.
More videos please! Thanks
Thanks for the video but let's save some time
1/2 tangent of your degree x gap of pipe.
Add or subtract from your 1st mark depending on if it's the shortest or longest your starting with.
Also this should work the same for kicks
Does this formula works for all parallel run? Like kick 90s?
Why are you using a protractor instead of the degree markings on the bender...Just curious
