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. The floor box accommodates dual services through the use of two sets of parallel aligned conduit hubs and a divider which is insertable into the housing interior between the two sets of conduit hubs. The closed top of the housing acts as a concrete cover during the pouring of the floor, and as a temporary debris cover after it is cut off but prior to activation of the floor box. Gradient markings on the interior of the floor box provide a quick and accurate measurement of interior floor box volume for inspection and building code compliance.
