Preparation Details).
2. Fire damper and sleeve assemblies 80 in. W x 50 in. H
(2032mm x 1270mm), 50 in. W x 80 in. H (1270mm x
2032mm), or 40 in. W x 100 in. H (1016mm x 2540mm)
and smaller only require retaining angles on one side
of the partition (See Figure 3 and Figure 4). Retaining
angles must be attached to the sleeve and the partition.
Larger damper assemblies require retaining angles on
both sides of the partition. Retaining angles must be
attached to the sleeve.
• Retaining angles for 1½ hour rated dampers with a width
and height 48 in. (1219mm) or less must be a minimum
of 20 ga. (1mm). Retaining angles for all 3 hour rated
dampers and all dampers with a width or height greater
than 48 in. (1219mm) must be a minimum of 16 gauge
(1.5mm). The leg of the retaining angle on the damper
sleeve shall be a minimum of 1¼ in. (32mm). The leg of
the retaining angle on the wall/floor shall be long enough
to cover the annular space and overlap the wall/floor by
at least 1 in. (25mm).
• Retaining angles must be attached to the partition and
sleeve using one of the methods shown below.
• tack or spot welds
• #10 sheet metal screws and bolts
• Drywall screws of a length such that the screw
engages the stud/track by a minimum of 1/2 in.
(13mm)
• A minimum of two connections per side, top, and
bottom, 12 in. on center maximum for openings of
