Step 1
Measure the distance to the obstruction.
Step 2
Measure the height of the obstruction.
Step 3
Review the offset bend chart to determine the angle of the offset,
the distance between bends, and the shrink.
Step 4
Add the distance to the obstruction and the shrink.
Mark this distance from the end of the conduit.
Step 5
The next mark you will make is the distance between
bends. Mark this measurement from the first mark
back to the starting end of the conduit.
Step 6
Place the conduit in the bender with the first mark aligned
with the arrow.
Step 7
Bend the conduit 45°.
Step 8
Without removing the conduit, slide and rotate it 180° so that
the second mark is aligned with the arrow.
Step 9
Bend the conduit 45°.
Step 10
Install.
