Combination offsets (Figure 24)
Combination offsets are used to conform to the building’s
structure and change direction, using a small amount of space.
They are two different oriented elbows fabricated into a single
fitting. Forward or rearward directions are determined by the “T”
and “F” locations. Please refer to page 15. Minimum leg lengths
are listed in Table 30.
