Application Data

Damper Sideplate and Sleeve Dimensional Data

The drawings below illustrate the factory standard sideplate and sleeve mountings for the SMD-301. The standard "A" dimensions 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).

**On dampers 11 in. (279mm) high or less (12 in. (305mm)high or less if width is greater than 64 in. (1625mm)) with OCI option, sideplate is 16 in.

				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.
