Our MC45 Mount Canopy offers a stylish and durable way to mount Auroralight fixtures on existing 3" or 4" round, flush mounted electrical service boxes. The solid brass body and gasketed canopy in brass or copper offers maximum corrosion resistance and ensures a tight seal where it joins the mounting surface. The MC45 also features a proprietary screwless faceplate that eliminates twisted wires and visible mounting hardware. Available in shallow or deep versions with a choice of 1 or 2 hole cover plates, allowing the MC45 to be used in single or double fixture configurations. The MC45 mount canopy, manufactured exclusively by Auroralight, represents possibly the finest mounting hardware available in the world today.
