This sliding window lock is constructed of extruded aluminum with a non-marring vinyl insert and a steel thumbscrew, and it comes in a milled aluminum finish. The design of this lock is manufactured to fit on older style, metal framed windows €“ usually of single pane glass. These locks will not work with modern vinyl windows, as the vinyl inserts have only a narrow 1/8 in. opening. For vinyl windows consider using Prime-Line model numbers U-9809 or U-10547. Once the lock has been mounted and hand-tightened, finish by tightening thumbscrew with pliers to securely lock windows in closed or ventilating positions. These locks are easy to install and are used by many to increase the security of their home.
