The Flanged SleeveThe Flanged sleeve is a metal housing for the fire damper that the framed retaining angles are to be attached. Sleeves are required on all fire dampers mounted in fire-rated walls, floors or partitions. See the installation instructions for details. The sleeve and damper assembly may be fabricated at the factory, in a shop or at the job site. The sleeve will always be smaller than the hole in the fire rated barrier so it can expand and contract without an adverse effect on proper operation of the damper.
