Conduit Bender Guide
Conduit Bending Basics:
The line of Klein Tools conduit benders have been designed for performance and durability exceeding
the expectations of today’s professional. It is recommended to familiarize yourself with bending
concepts, techniques and learn the bender’s functionality to provide you a positive experience while
greatly improving the overall outcome of your project.
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.
To aid bending when performing a ground or air bend, the benders are marked with different alignment
symbols to help the operator create the bends necessary to accomplish any project. The symbols found
on the Klein Tools benders are the arrow, the teardrop, the star point and angle markings. These
markings are found on various sides of the bender head.
The 4 most common bends to know how to make are the 90° Stub-Up, Back to Back, Offset and the 3
Point Saddle bends. It is common to use a combination of the bender markings when making certain
tube profiles. Knowing the proper technique and method of making the bends will allow you to
accomplish most projects efficiently.
Things to remember while bending:
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.
