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 bend a 30 60 30 saddle?
For a 30-60-30 saddle, push the conduit until it lines up with the 60-degree line on the bender head. Slide the conduit down the bender head and rotate it 180 degrees. This will enable you to reach the first outside mark. Move the first bend past the bender head, sliding it away from your body, until the first outside mark sits on the bender head.

What is offset bend?
What Is an Offset Bend? One of the more common bends made in electrical conduits is the offset bend: a technique used to move a run of conduit a set distance to one side, up or down. It is very rare that conduit can be placed in a straight line along the entire distance needed.
The Basics of Bending Conduit — Part 1 | EC&M
Conduit bending is truly one of the fundamental tasks of the electrical construction industry. Whether EMT, galvanized rigid steel conduit, or intermediate conduit, you will need to bend it.
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!
How to bend conduit?
1. A proper bend is made by rolling the conduit about the bender in the conduit’s cradle using all foot pressure. 2. Use the correct size bender for the conduit size being bent. 3. Some over bending may be required to allow for spring back of the conduit. The resting condition of the conduit is to be at the final angle desired. 4. Measure and properly mark your conduit using the tables and information provided. 5. Floor bending: Make sure conduit is secure so it does not slide prior to bending. Apply ample foot pressure to the benders heel while minimizing the use of the handle as a lever but more of a guide. 6. Air Bending: Make sure handle’s hilt is secure on ground and is reinforced by your foot so it does not slide out. Make sure you are balanced and apply force close to the tool and your body controlling the tubing as you bend it around the bender’s cradle making sure the conduit does not slide in the bender head. 7. To prevent injury, always wear protective gear and do not over exert.
What is a saddle bend?
The three point saddle bend is a variant of the offset bend since it is an offset bend that returns to the original in-line run after clearing an obstacle. This bend is intended to bridge over obstacles such as existing conduit or plumbing running perpendicular to the intended conduit installation.
What is offset bend?
An offset bend is a style of bend that is built independently of the 90° stub and the Back to Back bend and is an important bend to know when running conduit. It is common to shift the conduit a certain distance while continuing to run parallel in the same direction as the pre-shift portion of the conduit. There are many situations that call for an offset bend. The most common uses of this bend are: staggered joists, running tight on a wall and offset into an electrical box and changes in elevation.
How to make a stub bend?
The stub bend is made by bending a piece of conduit into an L shape or 90° bend by placing the free end (short end) of the tube to a predetermined length as indicated in the diagram below. This is the most common bend and is a building block for other bends. Common uses for this bend are: Running conduit into electrical boxes, running conduit up or down walls, running conduit into walls through floors and ceilings and making inner and outer corner turns.
What is back to back bend?
The back to back bend is the next style of bend that is needed while running electrical conduit. In reality the concept is formulated by the need to know the distance from the backedge of a 90° bend to a fixed point down the conduit to mark for other bend operations to meet the installation requirement. As you will see it builds on the 90° stub bend and when done the most common use of this bend will look like an elongated U.
What are the different types of conduits?
Conduit come in two types, EMT and Rigid conduits and can be found in various sizes. Klein Tools provides conduit benders for EMT in ½”, ¾”, 1” and 1-¼” conduit and ½”, ¾”, and 1” Rigid conduit.
What happens if you bend conduit?
When the bend is done properly the conduit will lay flat and will fit inside the two surfaces measured.
