Abstract
An improved small profile hanger system for ceiling suspended lighting fixtures comprises a plurality of hanger assemblies having a support stem and a downwardly arced crossbar. The support stem and crossbar have a relatively small elliptical profile have two sets of wire holes, each set of wire holes having an inner hole and an outer hole overlapping the inner hole, the inner and outer holes defining an intervening gap narrower than the dimension of either hole. The holes are sized to receive an insulated wire; the intervening gap preventing the wire from crossing over into the adjacent hole. The wire holes of the support stem are in communication with the wire holes of the crossbar providing a fully enclosed wiring passage from a ballast box assembly installed above a suspended ceiling to energize a lamp in a diffuser depending from a pair of the crossbars.
