Engineered for heavy architectural sliding doors, wardrobe systems, and commercial pocket doors, this heavy-duty hydraulic soft-close damper mechanism provides controlled deceleration and reliable self-closing action for door panels up to 80 kg (176 lbs). Featuring a high-grade sealed hydraulic oil compression cylinder, an 85 mm extended damping stroke, and high-tensile steel tension springs, it catches moving doors, dampens heavy sliding inertia smoothly over 2 to 5 seconds, and pulls the panel flush into the closed position without bounce-back or slamming noise.

Key Features

• 80 kg (176 lbs) Heavy-Duty Capacity: Robust structural casing and reinforced internal components engineered specifically for heavy solid wood, composite, and framed glass sliding panels.
• Smooth Hydraulic Oil Compression: Precision-machined hydraulic cylinder delivers progressive, leak-free deceleration to prevent harsh end-stop shock and roller wear.
• 85 mm Extended Damping Stroke: Long braking travel decelerates moving doors gently over 2–5 seconds for an ultra-smooth, premium closing sensation.
• Self-Closing Tension Spring: 10 N pulling force securely pulls the door panel into the fully closed position and holds it firmly against drafts or accidental opening.
• 50,000 Cycle Durability: Rigorously tested to withstand 50,000 operational cycles in high-frequency residential and commercial hospitality settings.
• Complete In-Track Mounting Kit: Supplied with damper units, adjustable actuator trigger brackets, mounting screws, and adjustment hex key for concealed track installation.
