An elongated rigid wall mounted strip with a shelf receiving non-yielding channel or groove along the length thereof has resilient spring means acting on the bottom face of the shelf to fixedly retain the shelf in the channel. The strip has an upstanding backwall with apertures for receiving fasteners to secure the strip to a vertical wall or the like. The shelf receiving channel projects outwardly from this back and has a bottom leg wider than the top leg to underlie the shelf. This bottom leg has a resilient spring deflected and loaded by the shelf to wedge lock the shelf in the groove. A raised rib on the free end of the bottom leg bottoms the shelf as it is pushed into the groove permitting the shelf to be tilted so that its top face will fit under the top leg as the shelf is pushed into the groove to depress the spring on the bottom leg to a loaded level flush with the top face of the rib thereby securing the shelf to project perpendicularly or horizontally from the wall on which the strip is mounted. The spring may be an integral lip on the bottom leg or any one of a number of different separate spring configurations carried by the bottom leg. The top edge of the backwall is preferably grooved to receive the bottom edge of a picture, bookend or the like, and the back face of the backwall preferably has inwardly projecting top and bottom ribs or beads to bottom on the wall. The strip preferably extends the full length of the shelf but may be shorter than the shelf.
