Do you have a vertical sliding window sash lock in need of a new keeper? These sash lock keepers mount on the checkrail face of the outermost, upper sash of single and double hung sliding windows and work with locks like those of Prime-Line part number F 2767. They are constructed of diecast zinc and come in a corrosion-resistant, white-painted finish. Besides restoring the functionality of your window with a replacement lock keeper of this type, these keepers can help add peace of mind by restoring the security features on your vertical sliding windows. The cam-type lock mechanisms that are designed to work with these keepers draw them in firmly towards the lock bodies, providing your windows with tighter seals, better weatherizing, and increased security. Depending on the size of the sash, these keepers can be used as singles or in pairs. Each pack includes one keeper, installation fasteners, and simple instructions. Installation of these replacement keepers is easy and can be done with a simple handheld Phillips head screwdriver. Each keeper is constructed with 1 inch mounting hole centers, and they mount on vertical sliding windows where the checkrails (also known as "meeting rails") of both the inner and outer sash rest flush. Compare the style and dimensions of this keeper to those required on your sliding windows and order yours today.
