ABSTRACT:
A concealed cam lock and keeper both of which can be mounted within cavities in the check rails of the respective lower and upper sash of a double hung window. The concealed cam lock has only an exposed handle with a raised section of the housing closing off a notch required for assembly of the housing with the check rail. The handle of the check rail lock has an offset to cover any wood splintering that may have occurred in the check rail of the lower sash in forming the check rail for receiving the housing of the check rail lock.
The keeper is mountable in a cavity in the check rail of the upper sash at a location to permit mounting of weather stripping therebeneath and generally at the level of the lower edge of the window glazing and has downwardly inclined openings to receive fasteners for attaching the keeper to the check rail and which can extend into the check rail without interference with the glazing.
