2.The optional PLASTER-RING BRACKET (or "mud ring") is identical to the New Construction Bracket, with the addition of a circular offset, forming an edge guide for sheet rock plastering. The bracket has wings that attach to the building structure. Sheet rock is typically either precut or cut with a rotary cutting tool. The sheet rock hole is then plastered (or "mudded") up to the ring to create a seamless cutout.
