ABSTRACT:
A coupling is provided for connecting between an electrical conduit and an electrical device for enclosing electrical wires passing therebetween, when the conduit and the device are laterally offset as well as spaced apart from each other. The coupling comprises at least first, second, and third hollow tubular members extending along first, second, and third axes respectively and joined end to end by at least a pair of ball and socket joints to form a unitary structure having relatively smooth interior walls forming a passageway for accommodating passage of electrical wires therethrough.
The joints are angularly adjustable in any plane aligned with said second axis to permit alignment of said first, second, and third axes not only in coalignment with each other, but also said first and third axes displaced one from the other by an offset distance corresponding to said lateral offset.
