Abstract
A track for conveyor chain is provided by a plastic member having sides and a flat cross web supported by a U-shaped channel to provide a low friction guide way for both the upper and return runs of the chain. The plastic guide way for both runs can be a pair of identical members or a single extrusion. The guide way and channel can be factory assembled in units of suitable length and mounted to the conveyor track at the point of installation with use of simple tools and without requiring any special skills.
