Overview

The Ningbo Dimon Telescopic Synchronized Sliding Door Hardware Kit is an engineered multi-panel sliding system designed for interior room dividers, pocket doors, conference rooms, kitchen partitions, and commercial patio enclosures. Utilizing an ultra-smooth toothed timing belt linkage combined with dual-directional hydraulic soft-close dampers, this system allows moving one door panel to automatically and smoothly glide all subsequent panels in unison—both when opening and closing. Built with heavy-duty bearing hanging trolley rollers and silent guide tracks, it delivers fluid, whisper-quiet operation across 2-door, 3-door, 4-door, 5-door, 6-door, and bidirectional counter-opening (bi-parting) configurations.

Key Features

• Synchronized Telescopic Belt Drive: Industrial-grade reinforced toothed timing belt mechanically links adjacent door panels, enabling sequential, proportionate movement with effortless fingertip glide.
• Integrated Two-Way Soft-Close Buffering: Heavy-duty hydraulic dampening actuators provide cushioned deceleration at both open and closed positions, eliminating slamming and safeguarding fingers.
• Upgraded Silent Buffer Triggers: Equipped with vibration-dampening buffer trigger pads that cut opening/closing impact sound by over 50% for quiet residential and corporate environments.
• High-Load Bearing Hanging Rollers: Precision-machined multi-wheel steel and high-density POM/nylon trolley rollers ensure smooth, balanced weight distribution with zero sag.
• Comprehensive Linkage Options: Specially configured kits for 2-door, 3-door, 4-door, 5-door, and 6-door cascading runs, as well as 2+1, 3+1, and double-opening counter-directional setups.
• Ceiling & Pocket-Door Compatible: Mounts inside top overhead tracks for a threshold-free floor opening, preserving seamless room flooring transitions.
• Complete Assembly Hardware: Includes hanging trolley wheels, soft-close dampers, toothed synchronous belt, door connector brackets, floor guides, wrenches, and fastener packs.
