The attractive PCS grille is molded ABS protected by UV inhibitors and has real eye appeal. Visually identical, the LCS features a heavy-gauge steel grille equipped with metal studs thereby showing only 4 visible mounting screws. Both are finished in non-reflecting ceiling white. Each installs easily using the BBX8B steel backbox and BRG-8B tile bridge. LCS8+T and PCS8+T models are shipped with four 1-1/2" white Phillips head screws.
