The mounting bracket support has a track (1) formed from two parallel rails (4,5) with flat tops (6,7). The tops extend on either side of the rail, leaving a slot between. The mounting bracket (20) for the equipment has a flat base (21,22) and arms (24,25) that extend forward to clip over the equipment and lock it in place. The centre of the base has a reinforced area surrounding a central hole. A screw (40) passes through the hole, and engages a nut (50). The nut is rectangular in shape, with the narrow dimension passing through the slot in the track. The longer dimension corresponds to the separation of the rails. As the screw is rotated the nut rotates till its longer dimension locks in the track.
