Abstract: A unique component furniture assembly for securing furniture components in wall furniture systems comprises a light-weight metal track, along which glides a novel fastening assembly which receives screws, threaded support posts and the like and to which a given furniture component is secured. The fastening assembly includes a block, preferably a plastic nut, carried by a basket. The block is suspended within the basket by a coil spring or other bias means. Relative expansion of the block and the basket by action of the spring causing contact with inner surfaces of the track causing the fastening assembly to remain stationary, though moveable on the track. The present furniture assembly further includes a plurality of selectively spaced detents, preferably raised protuberances, on the inside bottom surface of the track which function to lock the fastening assembly to the track and are used to align fastening assemblies on adjacent and opposing tracks.
