Bending Instructions

Single Bends (Stubs and Kicks)
1. Measure the length of the required stub.
2. See the Minimum Stub on the Deduct Table. The
required stub must be equal to or longer than the
Minimum Stub.
3. Measure and mark the stub length on the conduit.
This is the Stub Length Mark. Subtract the Deduct
from this mark and make a new mark. This is
Bending Mark 1.

4. Align Bending Mark 1 with the front edge of the
hook and bend the conduit.
Note: When the operator presses UNLOAD, the conduit
may spring back a few degrees. Compensate by over-
bending as shown in the Scale Reading Table.
