Special Bending Information

Laying Out Bends
The following illustrations and instructions show the most common bends. See the Special Bending Information
Chart for precise bending dimensions.
Stubs
HEIGHT
1. Select the size and type of conduit. Determine the height of stub and the angle of bend.
2. Find the chart that corresponds to the size of conduit selected in Step 1.
3. Under the column labeled ANGLE, find the angle of bend. Find the intersection of row Y and the appropriate
column H. The number at this intersection is the dimension Y. Place the bending mark Y inches from the end of
the conduit.
4. See the Operation section of this manual.
Offset
An offset is used to route the conduit around an obstruction. To make an offset, two equal bends are required. The
distance between the two bends is the center-to-center distance. This is represented by L1 in the bending tables.

BEND
LENGTH
HEIGHT
1. Select the size and type of conduit. Measure the height of the obstruction and the distance labeled LENGTH.
Determine the angle to be used.
2. Find the chart that corresponds to the size of conduit selected in Step 1.
3. To the right of the size and type of conduit, find the dimension labeled X. Subtract X from LENGTH. Place the
first bending mark this distance from the end of the conduit.
4. Under the column labeled ANGLE, find the angle of bend. Find the intersection of the L1 row and the appropriate
HEIGHT column. The number at this intersection is the dimension L1. Place the second bending mark L1 inches
from the first bending mark.
5. See the Operation section of this manual.
