Stainless Steel Casement Door Transmission Lock Espagnolette for Sliding Door

Its components include:
Main lock body: This is the core structure of the door lock, containing the latch and lock cylinder mounting position, and is responsible for the opening and closing and locking functions of the door;
Lock body panel: Installed on the side of the door, used to cover the lock body and allow the latch to extend;
Black retaining clip: An accessory used to assist in fixing the lock body or panel;
Screws: Fasteners used to fix the lock body and panel to the door.

The main body is a long, rectangular metal structure (marked "25mm" to indicate the compatible window sash groove width), with a brushed surface finish (wear-resistant and matching the appearance of doors and windows);
The hexagonal socket in the middle is the adjustment/linkage point, which connects to the window sash handle. Rotating the handle drives the locking points on both sides of the lock body to extend and retract;
The locking points at both ends (metal parts with clips) are embedded in the lock seats of the window frame, achieving a tight locking of the window;
The screw holes on the surface are used to fix the lock body in the groove of the window sash.

Effortless and smooth operation: The lock body features a precise internal transmission structure, ensuring smooth and jam-free movement of the locking points when the handle is turned. Opening and closing the window is effortless, making it easy for the elderly and children to operate.
Visual locking feedback: When the locking points are fully engaged in the window frame's lock seat, there is a clear "click" sensation, allowing for visual confirmation that the window is securely locked, preventing the safety hazard of accidentally leaving the window unlocked.
Performance and durability advantages:
Enhanced window sealing: When the locking points engage in multiple directions, they tightly press the window sash against the window frame's sealing strip, significantly improving the window's windproof, waterproof, and sound insulation performance, making it especially suitable for high-rise buildings or rainy areas.
Durable and robust materials: Made of stainless steel with a brushed surface finish, it is rust-proof and scratch-resistant. Even when exposed to humid and sunny conditions by the window for extended periods, it resists deformation and corrosion, ensuring a long service life.
