Offsets (Figure 23)
An offset is used to avoid obstacles and to conform to the
building’s structure. It is two elbows fabricated into a single fitting
for use where space restrictions prohibit the use of two standard
90° elbows. The minimum leg lengths are listed in Table 28
and Table 29.
ote:N All dimensions are to the centerline of the Pow-R-Bridge.
