Figure 40: - Wall Guide Heavy Duty (WGHD)

HEAVY DUTY WALL GUIDE (WGHD) 

The Heavy Duty Wall Guide is designed to complement the Heavy Duty 

Wall Support (See Figure 40). 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.

 

- Can be attached to combustible wall

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.

Figure 41: - Full Angle Ring (FAR)

HALF ANGLE RING (HAR) 

A Half Angle Ring is used as a saddle in horizontal or sloped runs.
