White-Painted Diecast Construction Sliding Door Lock for 1/4 In. x 2 In. - PRIME-LINE U 9817 Single Pack

Constructed from durable diecast material, the Defender Security door and window lock arrives in a crisp white coating. Primarily designed to fortify sliding doors with protruding metal fins, not exceeding 1/4 inch in width, it functions seamlessly on both traditional and sliding windows. Its dual-purpose design caters to both the fully-closed and slightly-ajar position for ventilation, ensuring child safety by preventing unintentional openings. Equipped with two tamper-proof, double hex security screws and a wrench, installation is hassle-free.

Featuring an upgraded cast aluminum build, another sliding door lock boasts enhanced gripping strength with its accompanying double hex security screw and wrench. This lock offers robust protection by securing the window in either the closed or open-for-airflow state, effectively guarding against accidental access by children. Compatible with metal-framed sliding doors and vintage metal-framed windows, it adds an extra layer of security.

Both these locks cater to sliding patio doors and windows with metal fins measuring 1/4 inch or less in thickness. Notably, they incorporate counter sunk Allen drive fasteners for a robust and reliable hold, ensuring a sturdy installation.

Enhanced with a sleek white-painted finish, this high-security sliding patio door and window lock delivers both aesthetics and functionality, making it an ideal choice for homeowners seeking peace of mind.
