The Art of Conduit Bending

Conduit Bending or it may be more proper to call it the curving of tubing. The most popular raceway is the electrical metallic tubing, better known as thin-wall or EMT.

To make bends is to turn or force from straight to curve or angular. If conduit is bent at a sharp angle to where the conduit is kinked, it then makes the pulling of the wire more difficult.

To curve is to have or to take a turn, change or deviation from a straight line without sharp breaks or angularity.

The quality of one's work can not always be judged as it may be covered by walls, ceilings, etc. but exposed conduit work is there for all to see.

You don't have to be a rocket scientist or trigonometric major to bend conduit.

The only way you will actually learn how to bend conduit is by actually doing it. Actual; experience soon makes this operation simple and routine.

The student will not realize the full value of the information unless he reinforces his study with a reasonable amount of practical work.

Learn the bends that are made on the job with the complete Conduit Bending Program.


A ruler has 16 marks per inch. Each mark represents 1/16th of an inch. 12 inches equal one foot.

The metric measurements uses words like millimeter (mm), centimeter (cm), and meter (m).

A millimeter (mm) is .001 meters and .03937 of an inch (between 1/32" and 3/64").
Example: 4" would have 107mm (4"/.03937 = 101.6).

A centimeter (cm) is 01. meters and .3937 of an inch (approximately 13/32").
Example: 12" would have 305mm (12"/.03937 = 304.8)

A meter (m) is one meter and 39.37 inch (approximately 39 3/8").
Example: 10' would have 3.05m (12"/.03937 = 304.8).

There would be 100 centimeters in one meter (39.37/.3937 = 100).
Example: 4" would have 10cm (4"/.3937 = 10.16).

There would be 10 millimeters in one centimeter (.3937/.03937=10).
Example: 12" would have 30.5cm (12"/.3937 = 30.48).

There would be .1 centimeters in one millimeter (.03937/.3937 = 0.1).
Example: 5' would have 1.52m (60"/39.37 = 1.524).
