Hanging Door Soft Close Damper

Designed for overhead sliding doors requiring superior stability, our Heavy-Duty Suspension Damper integrates a patented linkage-hydraulic system to minimize door sway and ensure smooth, controlled motion. With a robust build (220×15×35mm), it supports doors weighing 20-40KG (Standard) and 40-60KG (Heavy Series). The hydraulic buffer, linked to a reinforced hook via a pivoting rod, works with an L-shaped guide track and U-shaped notch to create reverse damping, allowing door hangers to be mounted closer to the edge for optimal balance. Ideal for glass, metal, or composite doors in high-traffic residential and commercial settings.

Key Features

1. Stability-First Design: Linkage-connected hydraulic buffer and hook ensure reverse damping, reducing door swing during operation.

2. Edge-Mounted Optimization: Door hangers install near the edge for enhanced weight distribution and minimized wobble.

3. Guided Motion Control: L-shaped track and positioning pillar restrict lateral movement, ensuring smooth linear glide.

4. Dual Weight Capacity: Covers 20-40KG and 40-60KG doors (two series).

5. Spring-Assisted Reset: Integrated spring automatically resets the hook, maintaining consistent tension.

6. Corrosion-Resistant: Zinc-alloy frame and sealed hydraulic unit withstand humid environments (e.g., bathrooms).

7. Tool-Free Adjustment: Pre-aligned mounting holes simplify installation on overhead tracks.
