Model 1271G is a combination fire/smoke damper specifically designed for supply or return ducts that terminate at a grille. The sleeve with unique 3/4" (19) grille mounting tabs simplifies installation, saves on field labor and eliminates the requirements for unsightly front retaining angles which commonly protrude from behind the grille. A steel grille installs over and completely hides the mounting tabs. The damper is offset in the sleeve to accommodate a single or double deflection supply air grille, single deflection supply air register or a return air grille or register.
