Abstract
Abstract A removable lock panel has two springs extending out of it which engage the drawer guides in a cabinet whereby the panel can be inserted in the cabinet, the springs will engage drawer guide notches therein, and a drawer can then be placed adjacent thereto and locked. So long as the drawer is locked there is no access to the springs or other means to remove the panel. This panel construction along with its associated cabinet and drawer parts permits adding a lockable drawer or tray to an existing cabinet with a minimum amount of cabinet alterations and actually without the necessity of using fasteners (nails, screws, adhesives).
