What is a 90 degree bend?

Determine the _______ required mark on the EMT

Stub-Up

If I have 1/2" EMT and want a bend a 10"

Subtract 5" [10" - 5" = 5"] at 5" mark you would start the bend

If I have 3/4" EMT and want a bend a 26-3/4

Subtract 6" from 26-3/4" [26-3/4" - 6 = 20-1/4]

Measure from what end of the pipe?

The end with the 90' angle in it

Where can you find the stub-up amount?

Usually it's found on the bender

Back to Back bends

back to back 90' bends resulting in a "U" shape

The second mark on the EMT should be

the length "stubbed", subtracted from the length to the first mark

The first mark on the EMT should be

the total length to bend
