These round chrome plated bronze frames and covers are designed to secure access to cleanout plugs, valves, controls or equipment concealed in walls. They are fitted with anchoring lugs that secure the frame to the wall’s surface and simplify installation. The face-of-wall cover is designed for installation on openings in tile, masonry, or dry wall construction. The flush-with-wall frame and cover is intended for installation in plaster or wet wall construction and is installed as the wall is built.
