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

Flannery’s 2-Piece Expansion Reveal acts as a plaster expansion joint designed to allow for the minor movement that may occur within an interior or exterior stucco finish. The Expansion Reveal creates an aesthetic reveal similar to the Plaster Channel Screed and allows for a ¼” of movement. Expansion movement may be increased with Flannery’s selection of custom expansion reveals and extended flanges. Select sizes of Flannery’s 2-Piece Expansion Reveals are available with Aluminum Alignment Splices to ease the installation process and create crisp and clean butt joints and lines.
