A rail assembly is provided which includes a rail support bracket. The rail support bracket is an extruded member and has a rail receiving opening and a pair of legs. Each of the legs has a plurality of parallel locking wedge ridges transverse to the legs. The legs are capable of being received in a rail structure having locking wedge ridges at right angles to and positioned for engagement with the plurality of parallel, longitudinally extending, inwardly directed wedge shaped locking ridges. The assembly can also include first rail member and a second rail member, each having one end received in the rail receiving opening, and a wedge locking device. The wedge locking device has a first region force fit between an end of the first rail member and the bracket rail receiving opening and a second region force fit between one end of the second rail member and the bracket rail receiving opening. Through the force fit at least one of either the wedge locking device and/or the rail member is distorted, thereby locking rails in said bracket. In an additional embodiment the wedge locking device is an extruded plastic member and is distorted by the force between a rail and the bracket.
