Application data damper sleeve dimensional data The drawings below and corresponding table show the position of the FSD-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 installation 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 positioned at other locations within a range of 6 in. (152mm) to 12 in. (305mm) for the "A" dimension. 6 in. LH RH 11/2 in. max. 53/8 in. V aries 33/4 in. *With the exception of dampers 10 in. high (254mm) or less. NOTE: Entire damper frame is not required to be installed within the wall. The damper blades, when closed should be contained within the wall. Right hand drive is show n A 5 in.

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 requirements 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.
