Abstract
A sash lock assembly is suitable for use with a sash window assembly including an upper sash window and a lower sash window slidable within a master frame, the upper sash window having a keeper connected thereto. The sash lock assembly includes a housing adapted to be mounted on the lower sash window, a cam positioned within the housing, an actuator handle, and an anti-rotation device. The housing has an opening therein. The actuator handle extends through the opening in the housing and is connected to the cam such that the actuator handle and the cam rotate together between a locked position, wherein the cam is adapted to engage the keeper, and an unlocked position, wherein the cam is adapted to disengage from the keeper. The anti-rotation device includes a protrusion positioned on the housing. When the sash lock assembly is in the locked position, the protrusion engages an engaging surface on the actuator handle to prevent rotation of the actuator handle.
