Special Bending Information (cont'd)
Offsets: Controlling the Start of the Second Bend
(use this method when working toward an obstruction)
LENGTH TO END OF SECOND BEND
1. Select the size and type of conduit. Measure the height of the obstruction and the distance labeled LENGTH TO
END OF SECOND BEND. Determine the angle to be used.
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 the Z row and the appropriate
HEIGHT column. The number at this intersection is the dimension Z. Subtract Z from LENGTH TO THE END OF
SECOND BEND. Place the first bending mark here.
4. In the same column, find the row labeled L1. Place the second bending mark L1 inches from the first bending
mark.
5. See the Operation section of this manual.
Three-Bend Saddle
LENGTH TO CENTER
HEIGHT
1. Select the size and type of conduit. Measure the height of the obstruction and the distance labeled LENGTH TO
CENTER. Determine the angle to be used.
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 needed. Find the intersection of the Z row and the
appropriate HEIGHT column. The number at this intersection is the dimension Z. Subtract Z from the LENGTH
TO CENTER. Place the first bending mark here.
4. In the same column, find the row labeled L1. Place the second bending mark L1 inches from the first bending
mark.
5. In the same column, find the row labeled L2. Place the third bending mark L2 inches from the second bending
mark.
6. See the Operation section of this manual.
Note: The second bend angle will be twice the number of degrees as the first and third bends.
