Fully Die-Cast Zinc Alloy with Weather-Resistant, Wear-Resistant Pearl Chrome Plating
The entire handle is die-cast from high-strength zinc alloy, featuring a compact structure that resists prying and impact and is resistant to bending and deformation.

The product has passed a 500-hour neutral salt spray test and a 4H hardness abrasion test. The plating has strong adhesion and is resistant to rust, scratches, and peeling even after prolonged exposure to sunlight and rain outdoors, ensuring excellent weather resistance and making it suitable for long-term use on balconies and street-facing windows.
Three-digit combination lock structure with multi-layered security protection
