Offset Bends:
An offset bend is a style of bend that is built independently of the 90° stub and the Back to Back
bend and is an important bend to know when running conduit. It is common to shift the conduit a
certain distance while continuing to run parallel in the same direction as the pre-shift portion of the
conduit. There are many situations that call for an offset bend. The most common uses of this bend
are: staggered joists, running tight on a wall and offset into an electrical box and changes in
elevation.
1. Determine/measure the offset distance necessary to clear the obstacle and how far away the
offset will need to be bent from the end of the conduit.
2. Decide what angle you wish to make the offset bend and determine the proper values from the
Offset Formula Table. Calculate the proper values to mark on the conduit to clear the obstacle
and fit in the gap measured.
As an example, the offset distance of the obstacle is 6” and
the distance to obstacle is 20”. The installation allows for
a 45° X 45° offset bend. Note: The choice of degree is
usually the installer’s choice and most of the time the
installation location will determine what degree will fit.
