The most common type of 3-point saddle bends consists of a 45-degree bend in the center and a 22.5-degree bend on either side. To determine where to place the center bend along the conduit, add the shrink amount and distance measurement together. Write the number down as your center line measurement.
How do you make a 3 Point saddle with conduit?
1 When making a 3-point saddle, you should always create the center bend first. 2 Squat into the bend and bend your knees as you push on the conduit. ... 3 For a 30-60-30 saddle, push the conduit until it lines up with the 60-degree line on the bender head.
How do you use a saddle bend in Conduit?
When laying conduit across a flat surface, you might run into another pipe that’s perpendicular to yours. If this happens, use a 3-point saddle bend to smoothly get your conduit up and over the obstruction like a mountain peak. First, measure the obstruction and make some simple calculations to determine where each of the 3 bends should.
How do you measure a 3 Point saddle Bend?
The most common type of 3-point saddle bends consists of a 45-degree bend in the center and a 22.5-degree bend on either side. To determine where to place the center bend along the conduit, add the shrink amount and distance measurement together. Write the number down as your center line measurement.
How do you bend a 30 60 saddle?
The second outside bend should be a mirror image of the first outside bend. Once again, use your body to add steady pressure onto the end of the conduit to push it down until the bottom lines up with the 22.5-degree mark on the bender head. For a 30-60-30 saddle, make this final bend a 30-degree angle.
How do you measure and bend a 3 point saddle?
The steps to making a three bend saddle are:Measure the height of the object to be saddled.Measure the distance from the end of the conduit to be bent to the center of the object to saddle.Place mark on conduit at distance to center of object.Add 3/16" to the distance for each inch of saddle required.More items...

Why is it important to know how do you bend a 3 point saddle bend?
Bending a Three-Point Saddle. Three bend saddles are often used to cross or saddle a small obstruction that would prevent the electrician from installing conduit in a straight line.
What is the multiplier for a 3 bend saddle?
Multiply the adjusted obstruction height by 2.5 for the placement of the outside bends. To determine how far out each outside bend mark should be from the center line, take the adjusted obstruction height and multiply it by 2.5.

What is the minimum bending radius for 3 rigid conduit?
Flexible conduits such as flexible metal conduits and nonmetallic conduits have similar rules for minimum bend radii. Bends must be made so that the minimum radius rules are followed, i.e., four inches for 1/2-inch conduit, 4 1/2-inches for 3/4-inch conduit, etc.
What is 4 point saddle bend?
In its simplest form, a 4 point saddle is nothing more nor less than two offset bends a short distance apart. Normally used to cross larger obstructions than the 3 point saddle, they have a definite place on the job site. For saddles greater than about 3", a 4 point saddle is probably the way to go.
How do you calculate shrink in conduit?

What is the best conduit bending app?
iBend ensures accurate conduit bends by calculating the math for you, saving you time. You can even customize the app to mimic the exact bender you are using. The app is available for iPhones for $4.99 as well as Android phones for $2.99.
How do you bend an offset in conduit?
1:092:48There align the first pencil mark with the arrow on the conduit bender. And place the conduit andMoreThere align the first pencil mark with the arrow on the conduit bender. And place the conduit and Bender squarely on the floor. Use heavy foot pressure on the heel of the bender.
How to bend conduit?
Then, cut the conduit, scrape off any rough edges, and slide it into the bender so that the place you want the conduit bent lines up with the arrow.
What is conduit bender?
A bender is an essential for any conduit bending project. The tool should fit the correct sized conduit tube that you need to use. Before you start the bending process, locate any instructions on the conduit bender that may describe how much conduit should remain past the bend to the end of the bending shoe.
How to get rid of burrs in conduit?
Cut the conduit to the size you need, removing burrs from the end. Use a conduit reamer or knife to scrape the edges to get rid of any fragments, or burrs. Ensure that all burrs are removed before you install the conduit. Otherwise, this may cause a short or ground fault after the wire has been installed.
How to measure conduit length?
1. Measure the length of conduit you’ll need. Start from a corner or other orienting point, then measure from the corner to where the conduit will end (usually a converter box). Place a pencil mark on the conduit at the measurement where the corner should be.
What is a back to back bend?
Back to back bends. Two 90° stub up bends on opposite sides of the conduit, with both stubs moving in the same direction.
What is a dog leg on conduit?
Be careful about creating a dog leg when you shape conduit. A dog leg is where multiple bends on a line don't line up in the same plane. Examine the alignment in all directions before bending off.
How many bends are there in electrical work?
Experiment with different kinds of bends. A typical electrical job will require more than simply a 90° stub-up bend. In fact, there are dozens of different combinations of bends you can use. It's helpful to experiment with bending a couple of them. Remember that practice makes perfect!
