3 Steps To Bend a 90 Degree Using the Reverse Method
- Measure the length of conduit where you need the 90 to be and mark.
- Place the bender on the conduit with the hook pointing towards to short end and align the mark with the tip of the star.
- Place one foot on the conduit and the other foot onto the bender foot. Grab the handle and using foot pressure on the bender foot and bend the conduit.
How do I calculate the kick for a 90 degree bend?
Note: You may first want to make a sample bend, to determine the distance from the start mark on the bender to the center of the bend for the angle of kick that you have selected. Measure 20" from the back of the 90° bend. Subtract 1/2 the diameter of the conduit. In this case, 1/2" conduit is about 3/4" in diameter, so subtract 3/8".
Why should I learn how to bend a 90 first?
By learning how to bend a 90 first you will be better prepared when you start learning how to bend offsets, parallel offsets, and saddles. TAKE UP – This first thing you need to learn before bending a 90.
What is the reverse 90 degree bend method?
This method is also used in back to back 90 degree bends. When using the reverse method the take up deduction is no longer needed. This bend forms a short leg as if it were the stub and leaves the long stub on the ground as if it were the leg.
How do you bend a 90 in Conduit?
To bend a stub 90, you simply place the shoe of the bender (facing the end of the pipe), at the very end of the pipe. Press down on the shoe and the end of the conduit will bend straight up in the air. That’s it, just be sure to place your level on the pipe to ensure that your bend is exactly 90 degrees to the ground.

How to bend conduit with one foot?
Place one foot on the conduit and the other foot onto the bender foot. Grab the handle and using foot pressure on the bender foot and bend the conduit. Check the bend with a level to make sure it’s plumb. It’s really that simple.
How far can you bend EMT conduit?
Since EMT conduit usually comes in 10 foot sticks (120 inches), you’re maximum distance between two points for this type of bend is 108 inches. When making a back to back 90 it’s important to allow enough room for the handle and bender show to be clear of the the other bend.
How to make conduit bend plumb?
If you’re conduit bend isn’t quite plumb, you can take the end of the bender handle and insert it over the stub. You’ll need to either push or pull the handle depending on which way you need the stub to bend to make it plumb. It’s really that simple.
How to get conduit to spring back?
Grab the handle and using foot pressure on the bender foot and bend the conduit until it is just past being perpendicular with the floor. This is to allow for spring back. Spring back occurs when you release pressure on the bender – it’s slight, but it’s there.
What is a take up on a 90?
Take up is a amount of conduit length used to figure out where to place the marks on the conduit before the bend. Most hand benders have the take up stamped on the bender or on a sticker – usually on the bender handle.
What is back to back bend?
A back to back bend is making a U with the conduit. To do it right, you could use both the basic and reverse method depending on the lengths of the stub you need. When bending back to back 90’s the idea is to make the connection from one point to the other using a single stick of conduit.
What is the cosecant of 60 degrees?
Correction... The cosecant of 60 degrees is 1.155. So if you want to use 60 degree kicks, the distance between holes in your MDP needs to be 1.155 x distance between pipe centers.
Can you use a straight edge?
You can use a straight edge but you really have to have a good eye for that. You can also measure the o.d. Center will be have of that measurement
Is it better to keep the same kick angle?
Agreed . Maintaining the same kick angle will not only look better but is a lot easier to reproduce three other times . All you need to adjust is your kick placement . It's easier than it sounds . You'll get it .
Can center to center spacing be the same on both sides of the 90 on parallel kicks?
I think he's confused. Your center to center spacing cannot be the same on both sides of the 90 on parallel kicks. The high side grows in relation to the multiplier of the angle used
How to measure a 90 degree bend?
A forward 90 is a 90 degree bend made by measuring from the front side of a pipe (front being the side you’re looking at if you’re kneeling at the half way point of the pipe. The part of the pipe behind you is called the “back side” of the pipe. With a forward 90 you take a measurement from the end of the pipe and mark that measurement. If you need to bend a 90 to hit a wall or some arbitrary line, you’ll use this exact measurement to mark your pipe. From this measurement you’ll subtract whatever amount you need (depending on the size of the pipe) towards the end of the pipe you just measured from. So from your original mark you measure, AWAY FROM YOU, 6 inches with 3/4” EMT (electrical metallic tubing) and mark the pipe again. This mark is now your only important mark. The first mark no longer matters to us.
How to bend a 30 degree angle?
To bend a 30 degree angle with a conduit bender, you bend the pipe up from the ground until the 30 degree line on the bender is parallel to the pipe and floor. You would flip the bender over and repeat this step if you were trying to bend a 30 degree offset to overcome an obstacle.
How to bend conduit?
To bend a “kick” place your bender facing your 90, or facing away from the direction your pipe run is coming from. Once your conduit is laying in the bending shoe, push down with your foot slightly (with a tape measure held in front of your bend to measure the height of the kick) until the kick yields the desired clearance/height. That is seriously all you do.
What is the easiest offset to bend?
The easiest offset to bend is the 30 degree offset , and it is the one I choose most often because of speed and accuracy. The first reason I choose 30 degrees is that both of your bends are easy to gauge. When bending the offset, each bend results in the handle of the bender pointing straight up to the sky when you hit your 30 degrees. If the handle is level and perfectly perpendicular to the floor, you should look down at the 30 degree mark on the shoe of the bender and notice it lines up exactly with your pipe. Reason 2 for choosing a 30 degree offset is that the math is easy. Every offset angle has a specific mathematical multiplier that you use to achieve your result. You must stick to this multiplier when marking the distance between bends, if you want your offset to land exactly where it needs to. See below for a list of multipliers:
How to offset a pipe?
To execute a box offset, place the shoe of the bender at the end of the pipe, as you would a stub 90. Slightly press down on the shoe of the bender until the conduit is between the 10 and 22.5 degree marks on the bender. Once this is set, scoot the pipe back about a 1/2” to 3/4” of an inch behind the first bend and twist/spin the conduit 180 degrees to prepare for the next bend. Next you’ll do the exact same thing, bending the second bend between the 10 and 22.5 degree mark to match the first bend. Now your pipe should make a slight “Z” shape at the end. You should be able to put your tape measure down on the ground and measure roughly a 1/2” space below the end of the pipe and the ground. If it’s too much you may have to use the bender to take out a tiny bit of bend from both bends. If the measurement is too little, you may have to go back and bend each of the bends a tad more.
How to know what conduit bender to use?
To start off, every bender has stamped in it what type of conduit the bender is designed to be used for. A 1/2” bender will say “1/2” EMT Only” or something similar – usually located where the shoe meets the threaded end of the handle. If you flip the bender around 180 degrees, in the same spot there will be a stamp for what size takeoff you’ll need to use to achieve the proper bend with this bender.
How many degrees can you bend an offset?
There are multiple ways to bend an offset, and by ways I mean shapes. You can bend a 10, 22.5, 30, 45, and 60 degree offset with most standard benders. Most of these angles can achieve clearing the same obstacle, it just depends on how tight to the object you’d like to be, and what math you want to do to achieve your result.
What is the deductable size for a 1" bender?
The most common deducts are 5" for ½" conduit, 6" for ¾" conduit and 8" for a 1" bender. It is a function of the curvature radius of the bender and cannot be changed. The deduct for your bender should be stamped on the bender. How to Make a 90 - Degree Bend. Bender Size.
How many degrees does a conduit need to go around a tank?
The number of conduit required to go all the way around the tank, or 360 degrees, is 6,049.53 / 118.25 = 51.16. Divide the total angle to go around the tank, 360 by the number of conduits required, 51.16, to get the angle required to bend each length of conduit. 360 / 51.16 = 7.04 degrees for each length of conduit.
