International Classification:

E04B 272

US Classification:

52255, 527161, 52417, 52257

Abstract:

A trim piece for installing at a drywall external right angle corner which is provided with a bullnose corner bead includes an intermediate portion which wraps over the convexly curved portion of the bullnose corner bead and has two edges extending parallel to the edges of the flanges of the corner bead. Two leaves are attached to the intermediate portion of the trim piece at the two edges respectively. The intermediate portion of the trim piece has an interior surface at a first end matching closely the exterior surface of the corner bead and an exterior surface which is convexly curved at the first end and is right-angled at the opposite second end and provides a transition from the convex curve to the right angle between the first and second ends.
