An apparatus for positioning and mounting fixtures is described. At least one ring for insertion into a mounting fixture is provided. A disc having a center opening for receiving a fastening device is provided for each ring. The fastening device is installed through the center opening of the disc, then aligned through the ring in the mounting fixture with a pre-drilled hole in the mounting surface, and loosely tightened into the pre-drilled hole. The mounting fixture is then aligned to a desired position relative to the mounting surface, and the fastening device is tightened such that the conditioned underside of the disc fixedly engages the ring and the mounting fixture to the mounting surface.
