Abstract
A window lock assembly accomplishing FER manipulation protection against unintended window opening without using additional components in the typical FER lock assembly by using a passive barrier system to help prevent access to both the lock cam and lock lever handle. The device can include at least one lock assembly mounted on the interior side of the window's inner sash and having a locked and unlocked position. The lock assembly engages with at least one keeper mounted on the outer sash to secure the window. The lock assembly housing has a barrier extending outward from the bottom surface which effectively helps to block access to the cam. The lock assembly housing also has a shroud which extends from the top and side edges which partially or completely covers the keeper and effectively helps to block access to the lever handle.
