Key Features
1. Dual Anti-Derailment System:
- Vertical Lock: Prevents wheels from jumping off tracks during sudden impacts or misalignment.
- Horizontal Guard: Blocks lateral shifts to keep doors on track even under uneven loads.
2. Heavy-Duty Load Capacity:
- Supports up to 80kg per set (e.g., solid wood, metal-clad, or glass doors).
3. Smooth & Silent Operation:
- Sealed industrial-grade bearings ensure noise-free sliding (<18dB).
4. Reinforced Construction:
- Zinc alloy housing + reinforced nylon wheels + 304 stainless steel springs.
- Corrosion-resistant coating for humid or harsh environments.
5. Universal Compatibility:
- Fits standard top and bottom tracks (width: 18mm-25mm).
- Adjustable height (±5mm) for easy alignment.
6. Easy Installation:
- Pre-assembled design with tool-free height adjustment screws.
