Lock Tongue Details: The crescent-shaped lock tongue is crafted from silver metal with rounded edges, preventing scratches to the window frame's latch groove during rotation. The high hardness of the metal material also ensures it is resistant to deformation and wear over long-term use.

Handle Details: The T-shaped long handle is made of black engineering plastic in one piece with a fine, non-slip texture, preventing slippage during grip. The metal connecting shaft between the handle and the lock tongue ensures smooth, seamless rotation and prevents loosening even after repeated opening and closing.

Base Details: The black plastic base has multiple pre-drilled holes of different diameters to accommodate various screw sizes and accommodate sliding window sash mounting holes of different widths. The thickened edges of the base ensure a more secure fit after installation and prevent breakage due to external pressure.

Overall Details: The lock body has a matte black coating, offering a smooth texture and resisting dust accumulation. It is highly compatible with PVC and aluminum alloy window frames, combining functionality and visual harmony.

Stable Locking, Strong Anti-theft:The metal crescent-shaped latch has a deep engagement, making it difficult to pry open once it locks into the window frame, effectively enhancing the window's security.

Smooth Handle, Effortless Operation:The T-shaped handle is ergonomically designed and features a metal pivot, ensuring smooth, jam-free operation, making it easy for the elderly and children to use.

Durable Material, Not Easily Damaged:The engineering plastic body is wear-resistant and anti-aging, while the high-hardness metal latch prevents deformation, rust, or breakage even after long-term use, ensuring a long service life.

Wide Compatibility, Easy Installation:The base features multiple mounting holes to accommodate sliding windows made of various materials such as PVC and aluminum alloy. The screw holes are adjustable, making DIY installation easy.

Understated Appearance, Versatile and Aesthetically Pleasing:The matte black surface has a delicate texture and blends seamlessly with various window frame colors, preserving the overall visual appeal of the window.
