A vertically adjustable sash lock is described that improves the seal of windows. The vertically adjustable sash lock may include, for example, a housing configured to be coupled to a first window sash and a rotatable cam configured to rotatably engage with a keeper bracket coupled to a second window sash. A vertical member may be positioned through a threaded aperture of the rotatable cam. A knob coupled to the vertical member may drive a rotation of the vertical member, causing a vertical position of the rotatable cam relative to a bottom surface of the housing to adjust accordingly.

A locking device for a container having a hinged lid, comprises a base unit adapted to be fixed to the container and a pivotable unit mounted to the base unit and pivotally movable between open and closed positions. The base unit includes a locking mechanism comprising a casing, a rotatable shaft, a blocking member fixed to the shaft and disposed in the casing, and a rolling member. The pivotable unit is mounted to the shaft of the base unit. The rolling member is provided to move within the casing between a blocking position wherein the rolling member blocks movement of the pivotable unit relative to the casing to prevent unauthorized opening of the lid, and a release position wherein the rolling member moves away from the blocking member to permit the movement of the blocking member relative to the casing thereby permitting opening of the lid.

A bar security system is an apparatus that is used to restrict access to a container. The bar security system includes an upper bracket, a lower bracket, an elongated support structure, a locking mechanism, and a height-adjustment assembly. The upper bracket and the lower bracket are structural elements that define reference points of the bar security system and used to secure the bar security system to a container such as, but not limited to, a storage cabinet. The elongated support structure is used to restrain items that are positioned within the container. The locking mechanism is used to prevent unwanted users from accessing the items positioned within the container. The height-adjustment assembly is used to adjust the bar security system so that the bar security system can be used on a container of any size.
