Overview
Designed for effortless retrofit and non-destructive surface installation on residential and light commercial doors, the Surface-Mounted Adjustable Automatic Spring Door Closer provides reliable, hands-free self-closing. Constructed from high-strength extruded aluminum alloy with a solid steel push rod, this compact tubular spring closer converts standard swinging interior doors into automatic-closing barriers. An integrated hex-key tensioning hub offers four adjustable torque gears, allowing homeowners, property managers, and hospitality staff to fine-tune closing speed and latching force without removing the closer.

• Wide 150° Swing Clearance: Delivers unrestricted door opening up to 150°, accommodating wide pedestrian passage and furniture movement without binding.
• Solid Alloy Connecting Arm: High-rigidity steel rod with a low-friction polymer guide tip glides smoothly across the protective door strike plate to eliminate scraping and chatter.
