HEAVY DUTY WALL GUIDE (WGHD)
The Heavy Duty Wall Guide is designed to complement the Heavy Duty Wall
Support (See
Figure 3 2
). It is used as a lateral guide and
is installed
immediately below the outer closure band near the duct joint. The outer band
must be able to move away from the Heavy Duty Wall Guide when thermal
expansion occurs. 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.
WARNING:
RISK OF FIRE - DO NOT ATTACH THE WALL GUIDE TO
COMBUSTIBLE CONSTRUCTION

HEAVY DUTY FLOOR GUIDE (FGHD)
A Heavy Duty Floor Guide is similar in function to a Heavy
Duty Wall Guide or Full Angle Ring, but has been modified for
use at floor penetrations. The angle brackets and straps hold
the FGHD centered in the floor penetration. Maximum floor
opening “X” is the Duct ID + 10”
Figure 36 – Heavy Duty Floor Guide (FGHD)
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.
Most supports incorporate the use of the Full Angle Ring due
to it providing structural integrity to the duct.

HALF ANGLE RING (HAR)
A Half Angle Ring is used as a saddle in horizontal or sloped
runs.

NOTE:
Both the Full Angle Ring and the Half Angle Ring are
designed to accept ½” threaded rod
