Abstract: A one-piece electrical fitting for connecting an electrical cable to a junction box, the electrical fitting formed from a single, flat blank of metal into a cylindrical connector body. The connector body includes a leading end having an exit bore, a trailing end, a cap, an inner bore, and one or more combination tangs including grounding tangs, locking tangs, and flanges extending radially outward from the connector body. The exit bore in the cap is offset to one side with cable retaining tangs on the fitting configured to push toward the exit bore in order to ease insertion of cables and conductors through the fitting.

Abstract: A grounding bushing with a central opening for electrically grounding a conduit, electrical metal tubing (EMT), or a pipe. The grounding bushing includes a stationary bushing portion and a rotatable bushing portion having slotted ends held together by mounting fasteners. The slotted ends permit rotation of the rotatable bushing portion away from the stationary bushing portion. After attachment to a conduit or similar structure, one or more mounting fasteners can be loosened to allow installation of additional wires through the central opening and into the conduit, EMT, or pipe. An electrically insulated liner extending around the entire inner periphery of the bushing prevents chafing or abrasion of any electrical wires by the end of the conduit.

Abstract: A flanged conduit support for running electrical cables between horizontal floors or vertical walls. The flanged conduit support includes a flange and a hub with a socket. A locking means on the flanged conduit support enables the locking together of two or more supports together in a spaced relationship. The locking means includes a male snap member with a tab and a tapered end and the female snap member includes a receiving slot. The flanged conduit support provides a means for rapidly securing a first end of conduit to a form and capping the opposite ends of the conduit to prevent the entry of concrete during the concrete pour. A removable flange portion may be removed after the concrete cures to provide one or more open pathways for running electrical cables through the horizontal floors or vertical walls.

Abstract: A reversible leveling ring for an electrical floor box. Multiple bolt-hole patterns to enable the leveling ring to accommodate more than a single style of floor box cover. The leveling ring includes a ring body having an inner periphery and a plurality of arms extending from the inner periphery. A first set of arms includes bores extending from a first side of the ring and a second set of arms includes bores extending from a second side of the ring. The bores in the first set of arms match a circular bolt-hole pattern that is of a different diameter than the bolt-hole pattern in the second set of arms thereby enabling an installer to flip the leveling ring in order to accommodate cover plates having two bolt-hole patterns.

Abstract: A poke-through floor box assembly adapted to be supported in an opening in the floor of a building. An intumescent layer in the assembly provides a fire-proof rating for the floor box to match the fire-proof rating of the surrounding structure. The assembly includes a can and an electrical box having separate compartments for housing low and high voltage components. A transition body extends between the electrical box and the can opening. A flange and cover provide a means for closing the assembly. Keystone holders on the transition body enable mounting of low voltage devices such as USB ports. EMT fittings provide a means for attaching electrical metal tubing to the can to carry power and low voltage signals into the can. Alignment features on both the electrical box and the transition body enable rapid assembly and installation of the electrical box at the job site.
