Bending Instructions
Laying Out One-Shot 90° Bends
1. Measure the length of the required stub. Refer to
Figure 1.
2. Find the minimum stub length for that diameter of
conduit on the “Deduct and Minimum Stub Length
Table.” The stub you require must be equal to or
longer than the minimum stub length.
3. Measure and mark the stub length on the conduit.
This is mark 1. Subtract the deduct from the stub
and mark the conduit. This is mark 2, or the bending
mark. Refer to Figure 2.
4. Insert the conduit into the bender so that mark 2,
the bending mark, lies at the center of the shoe.
5. Bend the conduit. To achieve the desired angle,
refer to the “Ram Travel Table for Common Bends”
in the “Bending Conduit” section this manual. Refer
to Figure 3.
