Abstract: A system for boarding up a store front window, and more specifically a corner bracket for use in removably supporting a panel respective an opening formed by a store front frame having corners. The panel temporarily closes the opening while avoiding damage to the frame, and preventing intrusion through the store front frame. The corner bracket has spaced parallel flanges connected by perpendicular load bearing wall members. One bracket is received at each corner of the store front frame and the load bearing wall members bear against adjacent frame members that form a corner. One of the flanges engage an interior surface of the frame while the opposed flange is attached to the panel. This causes the corner bracket to urge the panel against the exterior wall surface of the frame. The panel can be of an area greater than the area defined by the inner periphery of the frame to bring the marginal edge of the panel into engagement with the exterior frame face.

Abstract: A corner bracket comprising of two matching components held together by two bolts wherein as the two bolts are tightened, the two matching components will be urged toward each other thereby securely gripping a planar surface that is inserted between them.

The bolt will securely lock the corner bracket with the planar surface to the vertical supporting member inserted through the hole in the first component. The advantage of the present invention is that the force of the grip on the planar surface can be adjusted independently of the force of the grip on the vertical supporting member. Another advantage of the present invention is that the corner bracket can be used to secure a variety of planar surfaces with a relative large range of thickness.
