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 T O 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 22
1
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 and Y) at a
distance of 2
1
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 22
1
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.
