Smooth Finish Channel

Trim Purpose

Specs, MSDS, and LEED Information for Flannery Trims & Products

Flannery’s Smooth Finish Channels create an aesthetic reveal in any stucco wall system. Smooth Finish Channels break up plaster or stucco walls by creating horizontal and vertical reveal lines. Flannery’s Smooth Finish Channels are unique because they do not have the traditional plaster key at the reveal edge. With the plaster key removed, the plasterer can bring his finish coat right up to the reveal edge creating a clean sharp edge.

Flannery offers prefabricated intersections and corners for intricate building designs that utilize intersecting lines and bands on exterior walls. Prefabricated intersections and corners are mitered and then welded together at their attachment flanges, then vinyl tape is applied to the back of the reveal to prevent water intrusion. Factory welded intersections and corners come with 6” legs, however custom leg lengths can be ordered.
