Lighting fixture mounting post

摘要

A light fixture mounting post includes an upper threaded portion for attaching the post to a light shade and a lower portion for attaching light fixtures to the post. The upper threaded portion has left handed threads, and an O-ring and a shaped rubber washer residing between a post nut and the shade. A post flange limits the insertion depth of the upper threaded portion through the shade. The threaded segments include right handed pipe threads for tightly engaging the light fixtures. Embodiments include a continuous lower portion with straight or tapered threads and a segmented lower portion with reduced thickness spaces separating the taper or straight threaded segments allowing easy shortening of the lower portion.
