Damper Sideplate and Sleeve Dimensional Data
The drawings below illustrate the factory standard sideplate and sleeve mountings for the
If space constraints are a problem the "A" dimension can be varied between 53/8 in. (136mm) and 12 in. (305mm).

T* | Space Envelopes Required for Actuators |
S | and Accessories |
| Externally mounted actuators always require space |
| outside of the damper sideplate or sleeve. The “S” dimen- |
| sion 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 sideplate |
| or sleeve. “B” and “T” dimensions are worst case clear- |
| ance 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 avail- |
| ability above or below the damper sleeve is limited, each |
| damper size should be individually evaluated. |
