It features a durable, multi-strand stainless steel cable housed inside a sleek, weather-resistant ABS casing. This tool acts as a discreet alternative to traditional, bulky hydraulic hardware.

• Damage-Free Installation: Mounts instantly using heavy-duty, temperature-resistant double-sided adhesive backing to protect your walls and frames. Optional screw mounting accessories are included for heavy-duty setups. 
• High-Tensile Steel Cable: Equipped with a 1.2-meter rust-proof, plastic-coated S304 stainless steel wire rope. The cable is laboratory tested to survive over 50,000 to 80,000 smooth retraction cycles without snapping or fraying. 
• Consistent Closing Strength: Driven by a constant-force scroll spring providing reliable 800g to 1000g pulling tension. It securely closes lightweight interior doors, heavy glass sliding frames, and screen entries.
