90° STUBS
1. Measure the length of the required stub.
2. See the Minimum Stub Length formula on the
Deduct Table. The required stub 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 this mark
and make a new mark. This is Mark 2.
4. Align Mark 2 with the front edge of the hook and
bend the conduit.
Notes: When the operator presses “UNLOAD”, the
conduit may spring back a few degrees.
Compensate by overbending as shown in the
Scale Reading Table.
The shoe bends to 90 ° maximum.
