Exhaust and/or Supply Grille with Mounting Collar
or RSKC (exhaust only) Type Collar with Backdraft Damper
Step 1
Select the grille mounting point within the area to be ventilated. To ease installation,
locations of framing beams within the walls or joists supporting the ceiling should be
considered. Collar is provided with a perforated hanging strap for attachment directly to a
beam or joist. if the location of the grille does not allow direct attachment, a cross-member
mounted to the framing should be used.
Step 2
Place the mounting collar in the selected location and trace a circle onto the surface. From
the interior side of the room, cut through the surface. Please note: In order to assure a
smoother finish when mounting through a sheetrock or tile type ceiling, it is recommended
that a razor knife be used to make the cut.
Step 3
From within the attic or crawl space, place the mounting collar into the hole until the edge of
the collar is flush with the interior wall or ceiling surface. Attach collar to the support beam
with the 1" wood screws provided. Attach duct work. Please note: If beam or joist exceeds
the height of the collar, allow sufficient space between the collar and the beam to attach the
duct work. Also, when attaching flex duct to the collar/damper combination and an immediate
elbow is necessary, be certain that the elbow is installed with a "soft" bend to allow damper
to operate preperly.
Step 4
Snap the grille into the mounting collar. Grille
should be pushed tightly into place for an
airtight fit - Grille models DG, CG, HG, MGE
and MGS are designed for balancing airflow
(more open = more air, more closed = less
air).
