ABSTRACT:
A self-anchoring flush-type poke-through electrical wiring fitting which is adapted to be positioned in a floor aperture which is formed in a concrete building floor, for enabling the conducting of electrical power and telecommunication signals between the work spaces of multi-storied buildings. A retainer clip is engaged between a floor cup structure and disc-shaped fire barrier inhibiting displacement of the retainer clip. The retainer clip is constructed of a cold-worked stainless steel material, preferably such as type 302 or 304 annealed stainless steel possessing a minimal degree of resilience.
