Crescent-shaped lock body: Made of aluminum alloy, offering a smooth grip. Turning the lever rotates the internal arc-shaped lock hook, making operation simple.

Arch-shaped lock hook: A hidden arc-shaped structure beneath the handle; when rotated, it engages with the lock seat on the window frame, locking the window sash.

Mounting base: A plastic base with pre-drilled screw holes, allowing direct screw mounting to the window sash edge. Compatible with most PVC and aluminum alloy sliding windows.

Core Functions:

Basic Security: Locking the window restricts its sliding, effectively preventing intruders and meeting basic home security needs.

Windproof Positioning: The window can be fixed in any opening position, preventing it from sliding back and forth in the wind and improving stability.

Economical and Practical: Made of low-cost plastic, it's affordable and suitable for budget-constrained settings such as rental properties and older windows.
