Abstract

A trim piece for installing at a corner, either inside or outside, which has a bullnose corner bead. An exemplary embodiment of the trim piece includes a body that wraps over the convexly curved portion of the bullnose corner bead and at least one flange extending parallel to the edges of the flanges of the corner bead. The two flanges are attached to the trim piece at the two edges respectively. The trim piece has an interior surface matching closely the exterior surface of the corner bead and an exterior surface which is both convexly curved to match the convex bullnose corner bead and molded to match the exterior profile of the trim such that a smooth transition from trim board around the corner to the outer trim board results.
