Made of high-strength ABS, the PCS has the most eye appeal of any molded grille on the market and has a moisture resistant cone. Visually identical, the LCS features a premium, heavy-gauge steel grille with metal studs that shows only 4 visible surface screw heads. Both models are finished in non-reflecting ceiling white. Both offer long-term reliability and even coverage for distributed audio. Each installs easily using the BBX8B steel backbox and BRG8B tile bridge. The LCS8T and PCS8T models are shipped with four white, 1-1/2" Phillips-head screws.
