Hydraulic Buffer Mute Door Stopper Buffer Gold and Silver Options Key benefits Prevents door slams and reduces noise by controlling door movement with a hydraulic buffer. Protects walls, door hardware, and surrounding fixtures from impact damage. Durable metal construction for long service life in residential and commercial settings. Simple surface mounting with included screws for fast installation. What makes this product stand out Gold and black design uses pure copper and an internal hydraulic buffer that bounces back automatically after impact, returning the stopper to its ready position without manual adjustment.
