A channel screed comprises a first member having an internal channel defined by opposed walls extending from a base. The first member includes ribs within the internal channel that accommodate placement of a second member thereon. The first member having surface features that cooperate with surface features of the second member to provide an attachment therebetween. The first member includes fins projecting outwardly from the opposed walls to provide both an indication of building material thickness, and a mechanical attachment therewith. The second member covers the first member internal channel to provide a desired aesthetic appearance to the installed channel screed. The second member comprises a base with opposed walls, and includes flanges projecting from top edges of the opposed wall surfaces. When attached to the first member, the flanges cover up the internal channel, and the interface between the first member and the building material. |
