To Locate Bending Marks for Offsets
1. Measure the distance from conduit coupling to the edge of the obstruction and mark the conduit. This is mark 1.
2. See the Figure X Table. Subtract X inches from mark 1 and mark the conduit. This is mark 2.
3. Measure the height of the obstruction. This is the offset distance. Refer to the Offset Table to find the center-to-
center distance at the intersection of the top row (offset distance) and the first column (offset angle). Measure
and mark the center-to-center distance from mark 2. This is mark 3.
4. Insert the conduit into the bender with mark 2 aligned with the front edge of the hook. Make the first bend.
5. Without removing the conduit from the bender, rotate the conduit 180°. Align mark 3 with the front edge of the
hook and make the second bend.

To calculate the center-to-center distance for any other offset bend, multiply:
(for 15° bends) Height of the Obstruction x 3.86
(for 30° bends) Height of the Obstruction x 2
(for 45° bends) Height of the Obstruction x 1.4
