FACTORY SLEEVE OPTION

SSDFD-155 Fire Dampers are available in factory furnished sleeves. Sleeves are galvanized steel and are available in 10 thru 20 ga. (1mm- 3.5mm) thicknesses and lengths up to 36 in. (914mm).

“K” dimension specifies location of damper within the sleeve. Minimum is 4 in. (102mm), maximum is “L” less 4 in. (102mm), which allows for mounting angle installation and duct connection at each end of the sleeve. If “K” dimension is not specified, it will be provided as one half of “L” dimension (damper centered in sleeve).

Note: If using access doors, the door should be installed on the “K” side of the damper.
