Abstract: A panel fixture adapted to be inserted into a cavity formed in a panel, the panel fixture releasably receiving an accessory. The panel fixture can be mounted within a routed cavity in a panel or wall such that its faceplate can be substantially flush with the panel surface or wall surface to provide a convenient, randomly selected location for supporting an accessory such as a hook bracket or a shelf support bracket. The mounting of the panel fixture into the cavity simultaneously holds the panel against a wall structure. The faceplate has a slot located in an upper portion of the fixture. An accessory bracket to be inserted in the fixture may have a stepped upper plate part and a planar lower plate part and is mountable in/on the fixture with the stepped upper plate part of the accessory bracket inserted and confined in the slot of the fixture faceplate, and with the planar plate part of the accessory bracket fitting flat against the recessed planar surface of the body of the fixture.
