Main Material: Constructed of aluminum alloy with a white powder-coated finish, providing rust resistance and wear resistance, allowing for long-term outdoor exposure to sun and rain.

Arc-shaped Lock Hook: The arc-shaped metal structure hidden in the handle base precisely engages with the lock seat on the window frame when rotated, locking the window sash.

T-shaped Handle: The integrated design is ergonomic, providing a secure grip. Turning it smoothly rotates the lock hook, making operation simple and effortless.

Mounting Base: Equipped with pre-drilled screw holes for direct mounting to the window sash edge, compatible with most standard-sized sliding windows.

Anti-theft locking: Once locked, it restricts window sash sliding, effectively preventing outsiders from entering through the window and meeting basic home security needs.

Wind-resistant positioning: It can fix the window sash in any opening position, preventing the window from sliding back and forth in the wind and improving stability.

Economical and suitable: The light gray appearance blends naturally with the color scheme of most PVC and aluminum alloy windows, and its affordable price makes it suitable for replacing parts for older windows.
