Application Data

Damper Sleeve Dimensional Data
The drawings below and corresponding table show the position of the SSFSD-211 damper when mounted in a factory sleeve.
The standard mounting locations provide enough space for the mounting of actuators, controls and allow space for installa-
tion of retaining angles and duct connections.
The standard location of a damper mounted in a factory sleeve ("A" dimension) is shown below. The damper can be posi-
tioned at other locations within a range of 6 in. (152mm) to 12 in. (305mm) for the "A" dimension.

NOTE: Entire damper frame is not required to be installed within the
wall. The damper blades, when closed should be contained within
the wall.
Actuators and Accessories
Space Envelopes
Externally mounted actuators always require space out-
side of the damper sleeve. The "S" dimension illustrates
the clearance required for various available actuators.
On dampers less than 18 in. (457mm) high, actuators may
also require clearances above and/or below the sleeve.
"B" and "T" dimensions are worst case clearance require-
ments for some dampers less than 18 in. (457mm) high.
All damper sizes under 18 in. (457mm) high do not require
these worst case clearances. If space availability above
or below the damper sleeve is limited, each damper size
should be individually evaluated.
