Special Bending Information (cont’d)
THREE-BEND SADDLE
A three-bend saddle is used to route the conduit around
an obstruction. To make a three-bend saddle, three
bends are required; the first and third bends are an
equal number of degrees; the second bend is twice that
number of degrees.
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.
Note: The “angle to be used” is the first and third
angle of the saddle (not the second), as illustrated.
Refer to this angle when looking up the correspond-
ing information in the Special Bending Information
Chart.
2. Find the corresponding section of the Special
Bending Information Chart.
3. In the row at the top of the page, find the height of
the obstruction. Under the height, find the corre-
sponding L1, L2 and Z dimensions.
4. Mark the conduit as shown. Bend the conduit.
Note: After the first bend, do not remove the
conduit from the bender. Advance the conduit until
the second bending mark is aligned with the front
edge of the hook, rotate the conduit 180°, and make
the second bend. Then advance the conduit to the
third bending mark, rotate the conduit 180° again,
and make the third bend.
