Special Bending Information (cont'd)
Four-Bend Saddle
LENGTH
1. Select the size and type of conduit. Measure the height of the obstruction, the distance labeled LENGTH, and
the distance labeled STRAIGHT SECTION. 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 Z. Subtract Z from the LENGTH. Place the first
bending mark this distance from the end of the conduit.
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. Add L2 to the STRAIGHT SECTION. Place the third bending mark
this distance from the first bending mark.
6. Make the final bending mark L1 inches from the third bending mark.
7. See the Operation section of this manual.
U-Bends
1. Select the size and type of conduit. Determine the LENGTH and the HEIGHT.
2. Find the chart that corresponds to the size of conduit selected in Step 1.
3. Under the column labeled ANGLE, find 90°. Find the intersection of the Y row and the HEIGHT column that cor-
responds to the dimension labeled LENGTH in the illustration. Place the first bending mark Y inches from the
end of the conduit.
4. Find intersection of the L1 row and the HEIGHT column that corresponds to the dimension labeled HEIGHT in
the illustration. Place the second bending mark L1 inches from the first mark.
5. See the Operation section of this manual.
