How many degrees can you bend conduit?
If the bend is less than 90 degrees, you can put it back in the bender and bend it a little more. If you somehow end up with more than 12 inches on the horizontal, you can trim off the short end with a hacksaw or a tubing cutter. However, if you came up short, you'll have to start over with a new piece of conduit.

How to bend conduit?

What angle to bend conduit?
As a general rule, the shorter the offset distance, the smaller the angle. An offset of a few inches can use a 10º or 22.5º angle, but an offset of several feet may call for 30º or 45º. Smaller angles will "use up" less of your conduit, but may be more difficult to bend precisely.
What size bender should I use for conduit?
If you are using a hydraulic or power bender (recommended for conduit with a nominal size over 2 inches), find instructions for your specific bender model. Hickey benders tend to crush or kink EMT conduit. Use a bender with a curved track for the conduit to slot into.

What is the center bend on a saddle?
Bend the center. Most benders have a teardrop mark used for the center of a 22.5º–45º–22.5º saddle. Others may have three notches or marks along the rim, next to a "center bend" mark that looks like a semicircle with an arrow at the center. These three notches correspond to 30º, 45º, and 60º angles.
How to use offset bends?
1. Use offset bends to shift the position of the conduit. An offset bend requires you to bend the conduit in two places at opposite angles, usually between 10 and 45 degrees. Use this to shift the conduit to avoid an obstacle or change elevation, the continue in its original direction.
