Offset Bends
An offset is used to re-route the conduit to avoid an obstruction.
An offset consists of two equal opposing bends.
Two factors must be considered when selecting the offset angle. First, a
steeper bend angle will require more pulling force. Second, a shallower
bend angle will require more space.
Offset Angle
10° x 10°
22-1/2° x 22-1/2°
30° x 30°
45° x 45°
60° x 60°
Working Past an Obstruction
Example 1: Working Past an Obstruction
45° x 45°, 10 inches of offset
1. Determine the center-to-center distance. Use one of these two
methods:
• Find the appropriate multiplier in the Offset Table, Column 2.
(For 45° x 45°, the multiplier is 1.4). Multiply the height of the
obstruction by the multiplier (10" x 1.4 = 14).
• See the Greenlee Speed Guide for Offsets. In the Offset Depth Inches
column, find the row with the appropriate amount of offset. Find
the Center-to-Center column under the appropriate OFFSET ANGLE.
The distance shown at the intersection of the appropriate row and
column is the center-to-center distance. (Under Offset Depth Inches,
see the row labeled "10". Read to the right to find the Center-to-
Center distance under 45° x 45°. The number shown is 14".)
2. Mark the conduit as shown.
3. See the bending instructions.
