Abstract: One embodiment of a non-metallic floor box for use in electrical in-floor power and communication distribution systems for office buildings and the like includes a closed housing having a base, a top and vertically extending side walls defining an interior volume. The floor box prevents concrete from entering the housing during pouring and setting of the concrete floor, and is adapted to be cut off substantially flush with and parallel to the concrete floor in which it is set. The floor box housing includes gradient markings disposed on at least one of its side walls to indicate the interior volume of the housing and/or the depth of the concrete floor.

Abstract: A non-metallic floor box for use in electrical in-floor power and communication distribution systems includes a plurality of sets of vertically aligned indexing teeth formed in the interior of the housing side wall. An adapter ring is sized for insertion into the housing interior for supporting an activation kit above the housing interior compartment. The adapter ring has flanges extending from its periphery which are positioned to reciprocally mate with the vertical rows of teeth when the adapter ring is inserted into the housing interior compartment. The flanges and teeth are constructed to permit the ring to be inserted into the housing but to restrict its removal from the housing after its insertion therein. An activation cover is securable to the top of the adapter ring and extends beyond the perimeter of the side wall to limit the distance the adapter ring can be inserted into the housing.

Abstract: A non-metallic floor box for use in electrical in-floor power and communication distribution systems for office buildings and the like is disclosed. One embodiment of the floor box includes a closed housing having a base, a top and vertically extending side walls defining an interior volume. The disclosed floor box prevents concrete from entering the housing during pouring and setting of the concrete floor, and is adapted to be cut off substantially flush with and parallel to the concrete floor in which it is set. The floor box housing includes gradient markings disposed on at least one of its side walls to indicate the interior volume of the housing and/or the depth of the concrete floor.

Abstract: Each component includes one or more sets of pin and/or socket contacts each set being mounted on a contact block. The contact block has shield means surrounding the contacts and around each shield means in an outer housing. The shields and housing electrically and mechanically isolate the contacts.
