Damper Sideplate and Sleeve Dimensional Data

The drawings below illustrate the factory standard sideplate and sleeve mountings for the SMD-302M. The standard "A" di- mensions listed in the table provide adequate space for the mounting of actuators and controls.

If space constraints are a problem the "A" dimension can be varied between 53/8 in. (136mm) and 12 in. (305mm).

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.
