HEAVY DUTY WALL GUIDE (WGHD)
The Heavy Duty Wall Guide is designed to complement the Heavy Duty
Wall Support (See
Figure 55
). It is used as a lateral guide to prevent the
duct from flexing due to lateral loading . The proper location for a WGHD
is immediately below the outer closure band near the duct joint. The Heavy
Duty Wall Guide is bolted together with hardware provided to form a rigid
assembly.
NOTE:
- Seal joint with S-375 sealant above and below support if exposed
to weather.
FULL ANGLE RING (FAR)
A Full Angle Ring is used as a guide to prevent the duct from flexing due to
lateral loading. The angle ring is split for ease of installation. It is 1/8”
larger inside diameter than the outside diameter of the duct to allow
movement of the duct inside the ring.
