To Find Bending Marks - Offset - Greenlee 555 Instruction Manual

To Find Bending Marks - Offset

1. Measure distance from end of conduit to start of
bend and mark conduit (Mark 1).
2. Refer to Chart D for measurement "X". Measure this
distance from Mark 1 only and place Mark 2 on
conduit.
3. Refer to Chart C for distance between marks.
Measure this distance from Mark 2 and place
Mark 3 on conduit.
4. Layout of bends is now complete. Next, place
Mark 2 in line with front edge of the shoe hook and
make first bend.
5. Rotate conduit 180 degrees. Place Mark 3 in line
with front edge of shoe hook and complete second
bend.
Chart C
To locate the center-to-center distance of offset bending marks other than those listed in the offset chart, the following multipliers
should be used; multiply the height of offset required by 3.86 on 15 bends, 2 on 30 bends and 1.4 on 45 bends.
