Overview
Engineered for wide-span architectural partitions and commercial interior pocket/sliding doors, the 2+2 Bi-Parting Synchronized Sliding Door Hardware Kit delivers seamless, bi-directional telescopic movement with integrated two-way soft-close hydraulic dampers. Built around high-precision steel-wire reinforced timing belts and non-slip gear pulleys, pulling or pushing any single door leaf automatically synchronizes all four doors to glide in opposite directions, maximizing clear walkthrough openings with whisper-quiet operation.
Key Features
- 2+2 Synchronized Bi-Parting Linkage: Precision gear pulleys and high-tensile toothed timing belt synchronize opposite-direction dual-leaf sliding (opening from center to left and right simultaneously).
- Two-Way Hydraulic Soft-Close Dampers: Heavy-duty hydraulic cylinders absorb kinetic inertia at both the open and closed endpoints, decelerating door panels smoothly and preventing harsh frame slamming.
- Ultra-Quiet POK / Engineered Nylon Rollers: Premium POK polymer and high-grade nylon wheels with embedded precision sealed stainless steel ball bearings resist wear, roll silently, and prevent track scouring.
- Heavy Load Capacity: Rated for up to 60 kg (132 lbs) per individual door leaf (total system load capacity 240 kg / 528 lbs across 4 leaves).
- Versatile Track & Wheel Profiles: Available with Inclined Wheels, Round Wheels, and Concave Wheels to pair perfectly with custom or standard aluminum alloy top-hung tracks.
- Anti-Jump & Anti-Sway Guide Design: Floor-mounted concealed bottom guides and structural top bracket clamps eliminate panel swinging, shuddering, and accidental derailment.
