To Locate Bending Marks for Stubs
1. See the Stub Dimensions Table for the minimum stub length. The desired stub must be equal to or greater
than the minimum stub length.
2. See the Stub Illustrations. Measure and mark the stub length on the conduit. This is mark 1. Subtract the
deduct from the stub length and make mark 2. Mark 2 is the bending mark — locate this mark at the front
edge of the hook.
