FOUR-BEND SADDLE
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 table that corresponds to the size and type
of conduit selected in Step 1.
3. Under the column labeled ANGLE, find the appropri-
ate angle. Find the row labeled Z. In the row at the
top of the page, find the height (H) of the offset. The
number shown at the intersection of the Z row and
the appropriate H column 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. Bend the conduit.

1. Select the size and type of conduit. Determine the
LENGTH and the HEIGHT.
2. Find the table that corresponds to the size and type
of conduit selected in Step 1.
3. Under the column labeled ANGLE, find 90°.
4. Find the row labeled Y. In the row at the top of the
page, find the height (H) that corresponds to the
LENGTH. The number shown at the intersection of
the Y row and the appropriate H column is the dis-
tance Y. Place the bending mark Y inches from the
end of the conduit.
5. Find the row labeled L1, and go to the right to find
the height (H) that corresponds to the HEIGHT.
6. The number shown at the intersection of the L1
row and the appropriate H column is L1. Place the
second bending mark L1 inches from the first mark.
7. Bend the conduit.
