Description
The Lew Electric FB is a 5″ Round PVC Floor Box for concrete floor applications, offering 90 cubic inches of interior space for wiring connections. The Lew LRA-U Leveling Ring Adapter is sold separately, but needed to complete installation. The FB contains four conduit hubs (two 1″ and two 3⁄4″) and six reducers (two 3⁄4″ and four 1⁄2″). It also includes a concrete cap. Installation could not be easier. Once the concrete slab has been poured around the box, simply cut the remaining portion of the PVC box flush with the concrete.
The Lew Electric FB concrete floor box is ETL listed for United States and Canada installations, conforming to UL Standard #514C and CSA Standard #C22.2 #18 and meeting all applicable electrical safety standards.
