STEP 7 – Additional
Mounting Support
The Extension/Elbow Assembly must have additional mounting support.
90° Elbow Section:
Approximate weight 64 kg (142 lbs)
36" Extension Assembly: Approximate weight 51 kg (112 lbs)
shows an example of how the Extension/Elbow Sections can be
supported by suspension from a high ceiling. Points A, B & C show where chains
or high tension cables may be connected.

TIP
During an arc fault, the plenum will be subjected to a brief high pressure shock
wave. The Extension/Elbow assembly may experience dynamic loading. It is
important to account for dynamic loading when selecting supporting means
and materials.
