Fixture connection assembly
A light fixture connection assembly includes an internally threaded stem and two connectors that couple with a top surface and a bottom surface of a light fixture shade. Bores throughout the stem and connectors define a passageway for electrical wiring connected to a light sourced within the light fixture shade. The connection assembly reduces water-leakage into the hollow passage, and prevents electrical hazards and premature termination of the useable life of the light fixture.
