Window locks are suitable for sliding windows, sliding doors, and vertical windows. Before ordering, measure your window track to ensure the height is 0.55 inches (1.4 cm) and the width is less than 0.59 inches (1.5 cm). The window lock includes a vertical key designed to fit the center track of the window. Each window lock features two mounting holes for secure attachment to the window track, enhancing the stability of the locking mechanism. The surface is smooth and burr-free, ensuring safe handling. This keyed window lock fits most windows, patio doors, sliding glass doors, casement windows, awning windows, barn doors, garage doors, and similar applications. It helps prevent children from opening windows and sliding doors, promoting household safety. Installation is simple and requires no tools. Measure your window frame before purchase. The distance between the two mounting holes on the lock should be within 1.9 to 2.3 inches.
