This latch is new-old-stock (never been used) from this store, but the finish is beginning to show it age. It is heavy duty. The stout lever can be moved to lock into a keeper that is placed at the bottom of the window. The lever’s back plate measures 2 1/2 inches by 7/8 inches. The keeper measurers 2 5/8 inches by 3/4 inches. In the open position, the lever projects 2 inches.
