Arlington Industries’ FLBC8500 interlocking, nonmetallic, gangable floor box kits are designed for new concrete. They have connections on opposing sides so they can be locked together to create a two- or three-gang box that accommodates a brass or nickel-plated brass gasketed cover. Covers can be installed with the hinge on either side.
Arlington Industries’ FLBC6230MBLR cover kit is designed for installing receptacles flush in concrete floor boxes. It fits FLBC4500 and FLBC4502 boxes and other manufacturers’ 4 1 / 2 -in. concrete boxes. It has flip lids and includes a 6-in. brass cover, gaskets, receptacle and a leveling ring.
Arlington’s UL-listed, steel floor box kit includes a two-gang steel box, assorted gaskets and two receptacles—one power and one low-voltage or two power receptacles. It comes with round brass or nickel-plated brass covers with four flip lids to prevent water from entering the box. It installs flush in new or existing floors.
