BENDING
MARK 1
1. Select the size and type of conduit to be bent.
Measure the height of the obstruction and the
distance labeled LENGTH TO END OF SECOND
BEND. Select the angle to be used.
2. Find the chart that corresponds to the type and size
of conduit selected in Step 1.
3. Under the column labeled ANGLE, find the angle of
bend. 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 this intersection is the dimen-
sion Z. Subtract Z from LENGTH TO THE END OF
SECOND BEND. 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. See the bending instructions.

BENDING
MARK 1
1. Select the size and type of conduit to be bent.
Measure the height of the obstruction and the
distance from the end of the conduit to the center
(LENGTH TO CENTER) of the bend. Select the angle
to be used.
Note: The second bend angle will be twice the
number of degrees as the first and third bends.
2. Find the chart that corresponds to the type and size
of conduit selected in Step 1.
3. Under the column labeled ANGLE, find the angle of
bend needed. 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 this intersection is Z. Subtract
Z from the LENGTH TO CENTER. 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. Place
the third bending mark L2 inches from the second
bending mark.
6. See the bending instructions.
