Abstract:

A poke-through electrical fitting device for placement in a passageway such as a cylindrical hole through a wall, floor, or the like, which may be made of concrete or some other fire rated barrier. The fitting is designed to prevent the spread of fire from one side of the fire rated barrier to the other, to protect the conductors and to facilitate installation, by requiring minimum disassembly or assembly during the installation which may be accomplished by a single craftsman. The fitting includes a channel member through which the conductors pass. Pivotally coupled to the channel member are spring biased wing members which extend laterally and which include wedge points for binding engagement with the interior of the passageway. The wing members and wedge points may be released from the underside to facilitate removal of the fitting. A thermal barrier is included to inhibit heat transfer, and other sealing members are provided as a barrier to any products of combustion.
