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.

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.
