Conduit Bending Instructions (EMT Bender)


Accurate Stubs

Conduit Bending: Accurate Stubs

Subract take-up from desired stub height. This gives distance at which to place B on bender from the end of the tube. To make 11", 90° bend with 1/2" tube, allow for 5" for take-up as shown on diagram.
With 3/4" tube, allow 6"
With 1" tube, allow 8"

True Offsets

Conduit Bending: True Offsets

Line up arrow on either side of hook with guideline and make 45° bend in tube. Reverse tube in bender and adjust so that X is lined up with inch-mark on bender corresponding to depth of offset desired. Line up guide-line with opposite arrow and make second 45° bend. A true offset, in the sname plane, will result between X and Y.

Back-to-Back Bends

Conduit Bending: Back to back Bends

Make stub bend at X with guide-line centered on either arrow located on side of hook. Measure distances from X to Y on tube.

Reverse bender and put A on bender at Y on tube. Line up guide-line with opposite arrow than used when making first stub and make second bend.

Saddle Bends

Conduit bending: Saddle Bends

C -- Center of finished Saddle Bend
X -- Double of the diameter of round object from C
Y -- Double of the diameter of round object from C

Saddle Bend, Step 1

Saddle Bend step one: make a 45 degree bend

Place tube in bender so that "C" on tube is at notch on bender and make a 45 bend. (A 45 bend is reached when bender handle is at a right angle to the tube.)

Saddle Bend, Step 2

Saddle Bend step two: return bend, 22.5 degrees

Reverse tube in bender and place B on bender at X on tube. Make return bend of 22 1/2 . Duplicate procedure placing B on bender at Y on tube and complete saddle by making another 22 1/2 bend.

Finished bend neatly saddles round object

A completed Saddle Bend

Proper alignment of the guide-line with arrows on bender hook will result in the saddle being in a straight line.

To Straighten
