ABSTRACT:
A shock absorptive magnetic mounting support for a light fixture or the like object includes a base having a magnet mounted thereon for magnetically securing the mounting support to the underside of a metallic shelf or support surface. A support shaft upon which the light fixture is mounted has a threaded end portion received in an aperture in the base. A stop adjacent the threaded end portion limits the insertion thereof into the aperture. A rubber washer of a predetermined thickness is received on the threaded end portion of the shaft in abutting relation with the base. A nut, and, if desired, a lock washer, is received on the threaded end portion of the support shaft. The nut is tightened down against the rubber washer to secure the base and support shaft in a joined condition. The shock absorptive arrangement aids in preventing detachment of the magnetic base from the metallic shelf support in the event of the application of force to the upper side of the shelf.
