Setting Up Your Bends
The following describes a means for laying out the starting points for various types of bends. It will give very accu-
rate measurements for heights and bend angles commonly used.
Stubs:

1. Go to the following chart which is for the size and type of conduit you are to bend.
2. Look down to the ANGLE column until you come to the angle you want to bend to.
3. Look at the numbers in the row preceded by Y and pick the one that is directly under the height (H) you want.
4. Place a mark this distance from the end of the conduit.
5. Make your bend after positioning the front edge of the hook on your mark.
