Abstract:
1. A transition coupling arrangement, comprising: a concrete slab; a first piece of electrical conduit positioned in the concrete slab; a second piece of electrical conduit; and a transition coupling comprising a unitary coupling body having a generally tubular configuration and a single wall, including a first end defining a first opening for receiving said first piece of electrical conduit, and a second end defining a second opening for receiving said second piece of electrical conduit, with said coupling body extending between said first and second openings, said coupling being disposed in said concrete slab with the second end thereof being accessible to facilitate connection of said second piece of electrical conduit thereto, said coupling including a coupling securing member extending though said coupling body for engagement with said first piece of electrical conduit received in said first opening, said coupling body defining at least one inwardly extending protrusion positioned in spaced relationship to said first and second ends of said coupling body, said protrusion being engageable by said first piece of electrical conduit received in said first opening to facilitate positioning of said coupling with respect to said first piece of electrical conduit, said coupling body further defining at least on thread formation on one of inner or outer surfaces of said coupling body at said second end thereof to facilitate connection of said second piece of electrical conduit to said coupling.
