Things to Consider
- Also referred to as “Mutes”
- Makes the closing of a door quieter as it contacts the frame
- Provides a 1/8” gap between door face and stop of frame
- Prevents wear and tear on the door and frame
- 3 are mounted on the strike side single opening frames in the stop
- Located 6” from top to CL, 6” from bottom to CL, and at ASA CL (or frame CL on some)
- 2 are mounted on the head of paired opening frames in the stop
- Located 6” CL from frame CL for each leaf
Red Flags
- Critical for frames in new masonry walls to have silencers installed prior to installation to prevent mortar leakage through silencer holes
- Silencers and holes not required on frames using adhesive applied smoke seal weatherstripping

On single openings, the silencer is either in center of the opening, or at CL of strike | Silencers on paired opening are 12” apart (or 6” BS from CL of opening) | Double egress pairs have 1 silencer on each “side” of the head |
