Prime-Line Antique Brass Steel Window Lock 1 pk

This window flip lock is constructed of stamped steel and comes in an antique brass finish. This lock features a simple to install and simple to operate design for use on vertical sliding (single and double hung) wood windows. Upon mounting this lock on the stile face, towards the bottom of the upper sash, it creates a wedge between the top and bottom sash preventing the bottom sash to be lifted. The hinged wedge design can be swung opened to allow for opening of lower sash.
