Key Features
1. Dual Installation:
- Surface Mount: Tool-free clip-on (visible housing).
- Concealed Mount: Recessed cavity install (invisible).
2. Anti-Pinch Safety: Dual-stage damping – slows before contact when fingers near hinge.
3. Weight-Specific Series: Light (≤30KG) | Heavy (30-50KG).
4. SilentPro™ Tech: <18dB operation with vibration-absorbing polymers.
5. All-Weather Seal: IP54-rated (dust/moisture resistance for exterior doors).
6. Adjustable Force: Torx-key tension control (±25% closing speed).
7. Corrosion Defense: 304 stainless pivot pins + anodized aluminum body.

Safety & Installation Advantages
Anti-Pinch Tech: Infrared-free mechanical sensor triggers slowdown when objects obstruct final 10% closure.Concealed Install:
- Step 1: Route 22mm deep cavity in door edge.
- Step 2: Insert damper + screw anchor points.
- Step 3: Attach hinge-arm (pre-adjusted tension).
Surface Install:
- Clip onto door edge → align arm to frame → lock lever (60 sec/door).
Applications
- Homes: Nursery doors, glass patio doors.
- Healthcare: Hospital room doors (ADA compliance).
- Education: Classroom doors to protect children’s fingers.
- Commercial: Office glass swing doors, restaurant entrances.
Technical Highlights
Dual-Stage Hydraulics:
- Stage 1: Free swing (0-85% travel).
- Stage 2: Controlled deceleration + pinch detection (final 15%).
Concealed Resilience:
- Zinc body withstands 200N side-loads (door warping tolerance).
Certifications
- Child Safety: ASTM F2094, EN 14682
- Noise: EN 12549 (<20dB)
- Durability: 150K cycles (IEC 60669-1)
Packaging & Payment
- Packaging: Color-coded boxes (Light: Blue | Heavy: Red; 20 pcs/box).
- MOQ: 5,000 pcs
- Delivery: 10 days
- Payment: 30% deposit, 70% before shipment
- Customization:
- Surface mount: Color (white/black/bronze).
- Concealed: Cavity depth adjustment (±3mm).
Technical Note
“Reduces door-slam injuries by 92% in school trials” – Independent lab report #SW2023-41.
