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

Arc-Shaped Groove: Its arc-shaped groove design precisely engages with the arc-shaped hook of the crescent lock, achieving locking and securing of the window sash.

Mounting Holes: Pre-drilled holes on the base allow the lock seat to be fixed to the edge of the window frame with screws, forming a complete locking system with the crescent lock handle on the window sash.

Locking Mechanism: As the "engaging end" of the crescent lock, it engages with the handle's lock hook, forming the core component for achieving anti-theft and windproof positioning of sliding windows.

High Adaptability: The arc-shaped groove's dimensions match the lock hooks of most standard crescent locks, allowing direct replacement of old or damaged lock seats.

Sturdy and Durable: Made of high-strength aluminum alloy, it is not easily deformed or broken, can withstand repeated engagement pressure from the lock hook, and has a long service life.
