What offset bend means?
Offset bends are used to move a run of conduit from one plane to another. An offset is normally used to bend the conduit around an obstruction, or to relocate the conduit close to a structural member to make it easier to fasten the conduit.
Which way should the Bender face when bending a stub up?
In order to make a stub-up of a specified length, the take-up mark must be aligned with the arrow on the bender, and the hook of the bender must face toward the end of the conduit from which the measurement was made.
What is a saddle bend?

What is the multiplier for 10 Bend?
This is where the multipliers of 6 for 10 degrees, 2.6 for 22.5 degrees, 2.0 for 30 degrees, 1.4 for 45 degrees, and 1.2 for 60 degrees come from. This method is an approximation and is not mathematically correct, because it does not use the length of the arc of the bend.

When using a hand bender How must the Bender be positioned in order to form a 90 stub-up of a pre determined length?
Take-up is a measurement that is added to the desired stub length in order to make a stub-up. To figure out the take-up for a bender, make a mark on the conduit and align the mark with the arrow on the bender. Then, make a 90° bend, and measure the distance from the mark to the back of the 90.
What are the 4 types of EMT conduit bending tools?
The 4 most common bends to know how to make are the 90° Stub-Up, Back to Back, Offset and the 3 Point Saddle bends. It is common to use a combination of the bender markings when making certain tube profiles.
