Overview
The Surface-Mounted Silent Hydraulic Door Damper (Anti-Slam Buffer Closer) is an engineered, heavy-duty soft-close cushioning mechanism designed for interior wooden swing doors, rebated architectural timber doors, and hotel guestroom entrances. Constructed with a high-strength aluminum alloy casing and heavy-duty carbon steel mechanical linkage, this damper mounts cleanly to the top door jamb header and upper door face without requiring complex mortise cutouts. As the door closes, an anti-slip, shock-absorbing rubber roller arm catches the receiving strike channel, decelerating door momentum through precision hydraulic fluid resistance to pull the door silently and securely into the frame—completely eliminating slamming noises, draft-induced impacts, and pinched fingers.

Key Features

• Active Hydraulic Anti-Slam Soft-Closing: Internal industrial hydraulic buffer cylinder actively captures the swinging door panel in the final closing zone, softly dampening momentum to latch silently into the frame.
• Non-Mortise Surface-Mounted Installation: Fully surface-mounted design installs directly onto the door head jamb and top of the door leaf using standard screws—no routing, slotting, or structural door leaf modification required.
• Heavy-Duty Structural Construction: Built from premium die-cast aluminum alloy paired with high-tensile carbon steel pivot linkages, supporting solid interior doors up to 60 kg (132 lbs).
• Shock-Absorbing Roller Catch: Heavy-duty articulated arm features a wear-resistant nylon/rubber guide roller that engages the receiver smoothly and quietly, withstanding tens of thousands of cycles without wear or rattle.
• Handed Architectural Configuration (Left & Right Opening): Precision engineered in distinct Left-Hand and Right-Hand opening configurations to perfectly align with door swing directions and frame headers.
• Minimalist Matte Black Finish: Clean architectural powder-coated matte black finish blends seamlessly with modern interior woodwork, ironmongery, and contemporary doors.
