The MC45 Mount Canopy, part of an entire family of canopies from Auroralight, offers a stylish and durable way to mount fixtures. The MC45 is designed to fit all STANDARD: 3″ or 4″ round, flush-mounted electrical service boxes. The solid brass body and gasketed escutcheon machined from solid brass 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. It is available in shallow or deep versions with a choice of 1 or 2 hole mount plates, allowing the MC45 to be used in single or double fixture configurations.
