Zinc Alloy Casement Door Handle Lock
,Passcode Design Casement Door Handle Lock
,Dual Angle Casement Door Handle Lock
This casement door handle is available in two versions: a combination lock model and a standard non-combination model. It combines window operation with a combination lock for security, is compatible with inward-opening and inward-tilting windows, supports 90°/108° dual-angle rotation, and is compatible with aluminum profiles and PVC-U profiles.
Composite metal construction ensures high weather resistance and strength:
- Base is die-cast from zinc alloy, providing resistance to impact and prying forces
- Curved handle made of aluminum alloy for lightweight and comfortable grip
- Surface can be customized with various spray-coated finishes
- Passed 500-hour neutral salt spray test for rust and corrosion resistance
- Matching latch passed 500 Nm tensile strength test for secure locking
The combination lock model features a three-digit dial mechanism that allows users to reset codes themselves, eliminating the need for keys. Once locked with the code, the handle cannot be turned, effectively preventing accidental opening and unauthorized access.
- Moderate resistance dial with clearly marked, wear-resistant digits
- Easy operation for both elderly and children
- Prevents children from accidentally opening windows
- Blocks external prying attempts
- Non-code version available for lower floors and standard interior windows
