Engineered for architectural millwork, wardrobe manufacturers, and commercial sliding door fabricators, this 334 mm concealed sliding door soft-close damper mechanism delivers smooth, silent deceleration and reliable self-closing action. Featuring an internal pneumatic air cushion cylinder and a heavy-duty tension return spring, it catches moving doors, absorbs sliding inertia, and gently pulls the door into the fully closed position, eliminating violent slamming noise, preventing track derailment, and extending the operational lifespan of rollers and track hardware.

Key Features

• Smooth Pneumatic Deceleration: High-performance air cushion compression cylinder absorbs kinetic energy without oil leakage or fluid degradation over time.
• Automatic Self-Closing Action: Integrated high-tensile steel return spring engages the activator trigger to gently pull and hold the door firmly in the closed position.
• Silent In-Track Concealment: Low-profile 16 mm slim housing mounts seamlessly inside top sliding door tracks, wardrobe valances, or pocket door headers for a completely hidden appearance.
• Prevents Bounce & Derailment: Eliminates harsh end-stop collisions, preventing sliding panels from bouncing back open or jumping off the lower track guide.
• Durable Engineered Polymer Housing: Wear-resistant reinforced casing withstands hundreds of thousands of sliding cycles in high-frequency residential and commercial applications.
