14.0 OFFSET BENDING INFORMATION AND
CHARTS
1. Measure distance from end of conduit to start of bend and
mark conduit (“Mark 1”).
2. Refer to chart E for measurement “X” deduct this distance
from “Mark 1” and place “Mark 2” on conduit.
3. Refer to chart D for center to center 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 shoe hook and make first bend.
5. Rotate conduit 180°. Place “Mark 3” in line with front edge
of shoe hook and complete second bend.
NOTE: Figures are approximate.
To locate the center to center distance of offset bending marks
other than those listed in Chart D, use the following multipliers.
Multiply the height of offset desired by 3.86 on 15 degree
bends, 2 on 30 degree bends, and 1.4 on 45 degree bends.
NOTE: Figures are approximate.
