BENDING NOTES:
Thread handles into bender head as far as
they will go.
BENDING ON THE FLOOR:
For best results keep the conduit pinned to
the floor by applying constant pressure on
the foot pedal throughout the entire bend.
BENDING IN THE AIR:
Tuck the conduit under your
arm and use your foot to
keep the handle from
sliding on the floor. Keep
your hands and body
close to the bender
throughout the bend.
CORRECTING OVER BENDS:
There are two options for correcting
over-bends. One option uses the open
end of the handle as a “cheater” bar and
the second uses the hook area.

90° OR STUB BENDS:
BENDING ON THE FLOOR:
1. Measure stub height (x)
2. Subtract amount shown in chart from
stub height. Deduct amount is also
noted on bender (example: subtract 5"
for a 1⁄2" bender)
3. Mark conduit at final deduct location.
4. Line up mark on conduit with arrow
on bender. Make the bend.
BACK TO BACK BENDS:
1. Measure and mark distance on the
conduit from a fixed point (x) to the
back of the 90°bend (Y).
2. Align the mark (Y) on the conduit with
the star on the bender and make
the bend.
SADDLE BENDS:
This bend is used to avoid an obstruction,
such as a pipe.The most common bend is a
45°center bend and two 221⁄2°outer bends.
Another method of making a saddle bend is
a 60°center bend and two 30°.
1. Measure the height/diameter (D) of the
object to be crossed over.
2. Measure the distance (L) to the object to
be crossed over and add 3⁄16" to the
length for each inch of the object height.
3. Mark this distance (C) on the conduit.
It is the center point.
4. Make the outer bend marks (X andY) at a
distance of 21⁄2" x the object size. Mark
each from the center mark.
5. Align the center mark (C) with the “notch”
on the bender and make a 45°bend.
6. Align the outer marks (X and Y) with the
arrow and make a 221⁄2°bend.

OFFSET BENDS:
Offset bends are most commonly used to
feed into a panel box or to go around an
obstruction.The most common offset angle
is 30°due to the angle multiplier = 2.
1. Measure the height of offset (Z).
2. Measure the distance to obstruction (L)
and add shrink amount (chart below) for
each inch of offset. Mark the distance on
the conduit (X).
3. Using the offset height (Z) times angle
multiplier (chart below) subtract this
amount from the 1st mark and mark this
on the conduit (X).
4. Align the marks with the arrow and
make your bends.
