Overview

The Frameless Glass Sliding Door Soft-Close Roller Kit is an engineered, commercial-grade overhead hanger and damper system designed for smooth, silent operation in high-end shower enclosures, glass office partitions, and modern interior sliding glass doors. Featuring an integrated two-way hydraulic damper with a 65 mm buffer stroke, this system gently decelerates glass doors during both opening and closing cycles to prevent slamming, bounce-back, and glass vibration. Built with heavy-duty 4 mm brushed stainless steel glass clamps and silent POK nylon roller wheels, the kit supports frameless tempered glass panels up to 60 kg (132 lbs).

Key Features

• Integrated Two-Way Hydraulic Soft-Close: Dual-direction internal hydraulic piston mechanism provides quiet, controlled deceleration over a 65 mm buffer stroke at both opening and closing extremes.
• Silent POK Engineering Nylon Rollers: High-precision enclosed ball bearings encased in wear-resistant POK/POM polymer wheels deliver ultra-quiet, frictionless gliding without track wear.
• Heavy-Duty 4mm Stainless Steel Glass Clamps: Precision-machined, multi-layer electroplated and brushed stainless steel clamp plates securely grip frameless glass with embedded rubber isolation gaskets to eliminate glass drilling and prevent slippage.
• 60kg (132 lbs) High Load Capacity: Robust alloy carrier body and reinforced hanging bolts support heavy commercial and residential tempered glass panels effortlessly.
• Available in Round & Inclined Roller Profiles: Offers both round wheel and inclined wheel configurations to ensure optimal tracking and fit with various architectural overhead box rail profiles.
• Comprehensive All-in-One Kit: Includes two-way buffer pulley, secondary load-bearing hanger, limiters, floor swing guide, glass clamps, adjustment wrench, and mounting hardware.
