These grille access fire/smoke and fire dampers were designed to save labor. They feature: easy installation from only one side of the wall, requiring no retaining angles; out of wall installation for supply or return applications with grille outlets; integral full premeter grill mounting flange; access through the grille to the damper, actuator and other accessories and the elimination of unsightly fire-rated access doors.
