Section 2 Installation
Step 1
Measure the height of the obstruction.
This duct is 4″ tall.
Step 2
Measure the distance from the conduit to
the obstruction. The distance from the
center of the duct to the center of
the coupling is 20″.
Step 3
Calculate the placement of the center
mark. For every 1″ of obstruction height,
move the center mark forward 3/16″. The
center mark in this example is 20 3/4″
from the end of the conduit.
Step 4
Lateral marks are placed 2 1/2″ away
from the center mark for every 1″ of
obstruction height. Place one mark on
each side of the center mark. This
example requires the lateral marks to be
10″ from the center mark.
Step 5
Place the conduit bender handle on the
floor and secure it in place with your foot.
Place the conduit in the bender so that
the center mark is aligned with the rim
notch (or the teardrop mark). Bend the
conduit to 45°, being careful not to kink it.
Step 6
Without removing the conduit from the
bender, rotate the conduit 180° and slide
it forward (slide the first bend away from you)
until the lateral mark closest to you is aligned
with the arrow. Bend the conduit to 22 1/2°.
Step 7
Remove the conduit and flip it end-for-end.
Place it back in the bender with the second
lateral mark closest to you. Line up the
second lateral mark with the arrow and
bend the conduit to 22 1/2°.
Figure 4-24. The saddle bend consists of one 45° center bend and two 22 1/2° lateral bends.
