Commercial Door Silencers & Mutes
Reduce noise and prevent the annoying sound of metal-on-metal contact with our high-quality door silencers. Designed to be inserted into the stop of a door frame, these small rubber mutes—often called "door bumpers"—absorb the impact of the door closing. We stock standard silencers for hollow metal frames and screw-in versions for wood frames to ensure a quiet, professional environment.
How Many Silencers Do You Need?
For a standard single door, the industry standard is to install three silencers on the strike jamb (the vertical side with the lock). For a pair of double doors, you should install two silencers at the header (the top) for each door leaf.
Metal Frame vs. Wood Frame Silencers
It is critical to choose the correct type for your frame material:
- Hollow Metal (HM) Silencers: These feature a "cone" or "pneumatic" shape. They are pressed into 9/32" pre-drilled holes in the frame stop. Once inserted, the air pocket inside the silencer compresses to provide a soft landing.
- Wood Frame Silencers: These are typically flat or rounded rubber discs that are either self-adhesive or fastened with a small screw. They are designed to sit flush against the wood stop without the need for deep drilling.
Why They Matter for Facility Maintenance
Beyond just noise reduction, door silencers help maintain "latch bolt" alignment. By providing a consistent 1/16" to 1/8" cushion, they ensure the door sits snugly against the stop, preventing the lock from rattling due to air pressure changes or high-traffic vibrations.
