Additional Bending Instructions

The following drawings and bending tables are intended
to provide the information necessary to accomplish
the most common types of bends. The bending tables
contain conduit marking information.
STUBS
1. Select the size and type of conduit. Determine the
height of stub and 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 appro-
priate angle.
4. Find the row labeled Y. In the row at the top of the
page, find the height (H) of the stub. The number
shown at the intersection of row Y and column H
is the distance Y. Place the bending mark Y inches
from the end of the conduit.
5. Bend the conduit.

OFFSETS
An offset is used to route the conduit around an
obstruction. To make an offset, two equal bends are
required. The distance between the two bends is the
center-to-center distance.
When working past an obstruction, it is necessary to
determine the location of the first bend. The center-to-
center distance is then used to determine the location of
the second bend. When working toward an obstruction,
it is necessary to determine the location of the second
bend. The center-to-center distance is then used to
determine the location of the first bend.
Working Past an Obstruction
1. Select the size and type of conduit. Measure the
height of the obstruction and the distance labeled
LENGTH. Determine the angle to be used.
2. Find the table that corresponds to the size and type
of conduit selected in Step 1.
3. To the right of the size and type of conduit, find the
dimension labeled X. Subtract X from LENGTH.
Place the first bending mark this distance from the
end of the conduit.
4. Under the column labeled ANGLE, find the appro-
priate angle. Find the row labeled L1. In the row at
the top of the page, find the height (H) of the offset.
The number shown at the intersection of row L1 and
column H is L1. Place the second bending mark L1
inches from the first bending mark.
5. Bend the conduit.
