Overview
The Heavy-Duty Commercial Slide Track Door Closer is engineered with a sleek, low-profile slide arm channel and an integrated, adjustable 90° hold-open positioning block. Unlike conventional scissor-arm closers that protrude into hallway spaces, the linear slide-rail design aligns flush with the door frame, providing a modern, anti-tamper aesthetic ideal for high-traffic commercial storefronts, offices, and modern interior glass or aluminum doors. Featuring a precision-cast aluminum alloy hydraulic cylinder with independent dual-valve sweep and latch speed controls, it delivers smooth, controlled closing and reliable latching performance.

Key Features

• Concealed Linear Slide Arm Channel: Low-profile guide rail eliminates bulky protruding scissor arms, providing a streamlined, tamper-resistant architectural appearance.
• Adjustable Hold-Open Positioning (90° & Multi-Angle): Integrated internal mechanical stop block locks the door open at 90° (or custom set angles) for easy passage, loading, and ventilation, and releases with a gentle manual pull.
• Dual Independent Hydraulic Speed Regulation:
  • Closing Speed Valve: Adjusts primary sweep velocity from 180° down to 15°.
  • Latching Speed Valve: Regulates final closing acceleration from 15° to 0° to ensure complete latch engagement without frame slamming.
• Universal Non-Handed Mounting: Field-reversible body and track mount seamlessly on either left-hand or right-hand swinging doors in standard or top-jamb orientations.
• Heavy-Duty Die-Cast Aluminum Body: High-density cast aluminum housing with hardened steel rack-and-pinion internals and premium anti-freeze hydraulic fluid (-30°C to +50°C).
