Measuring a corner

Step-by-Step

To get conduit around a corner, first measure from the box to the top of the bend (distance A). Then subtract the bend distance and mark the conduit. (The bend distance for 1/2-inch conduit is 5 inches. For 3/4- and 1-inch conduit, allow 6 and 8 inches, respectively.) Slip the conduit bender onto the tubing and align it as shown. After making the bend, trim section B by holding the bent conduit in place for measuring, and cutting the end so it just reaches the box.

Making the bend

With one foot on the rear of the bender, pull slowly and steadily on the handle. Be careful. Tugging too sharply will crimp the tubing and you'll have to start over again with another piece. (Codes forbid installing crimped conduit.) Making crimp-free bends takes practice, so don't be surprised if your first efforts fail.

Bending an offest

When mounting conduit on a flat surface, you'll need to form an offset at each box. Offsets must be aligned with other bends in the tubing. A stripe painted along the length of the conduit helps you do this. First make a 15-degree bend.

Finishing the offset

Roll the conduit over, move the bender a few inches farther from the end, and pull until the section beyond the first bend is parallel to the floor.
