This Truth Hardware Casement Window Sash Lock by Prime-Line Products is constructed of diecast zinc and comes in a bronze-painted finish. It features a low profile design to remain in-line with the thickness of the window's sidestop trim. The height of this lock measures 2-3/4 inches. It has mounting holes spaced apart at 2 in. on center, and it comes complete with its keeper and installation fasteners. When the lever is activated, the locking cam engages the keeper, drawing the window tightly closed against the weather stripping.
