Abstract: A metal lath accessory comprising a metal lath attachment feature that includes a side wall, a first flange extending from the side wall, and a second flange extending from the side wall. The first flange comprises at least one barb that projects from the first flange towards the second flange. In some embodiments, the second flange comprises at least one barb that projects from the second flange toward the first flange. The barbs may be configured to engage a piece of metal lath that is inserted between the first flange and the second flange.

Abstract: A casing bead for constructing a wall structure includes a bead wall, a flange, and a removable leg. The flange extends away from the bead wall and is configured to receive a viscous construction material thereon to facilitate embedment of the casing bead within the viscous construction material to form part of the wall structure. The casing bead may be positioned adjacent to a frame member thereby forming a gap between the bead wall and the frame member. The leg is removably connected to the bead wall and configured to extend into the gap thereby inhibiting the viscous construction material from being introduced into the gap. Furthermore, the leg is configured to be selectively removed from the bead wall to reveal at least a portion of the gap to allow a user to introduce a sealant into the gap.
