To use this table: Find the gain factor by finding the intersection of the appropriate row ("tens" digit of the angle)
and appropriate column ("ones" digit of the angle). See example below.

Additional Pipe Support Locations
The 777 has four unmarked holes in the frame. These
permit bends closer to the end of the pipe or conduit.
Figure 4 shows the bending of 4" conduit with the pipe
supports on the left-hand end using one of these un-
marked holes. Use these unmarked holes for bending
a few degrees of offset, or kicks, in the conduit.
