ABSTRACT:
A support roller device for heavy curtains of the type used on curtain-sided cargo carrying vehicles wherein the roller has a pair of spaced wheels for engaging rails of a track member that has a downwardly opened slot between the rails. A guide block with longitudinally spaced flanges of a low friction material is positioned in the track slot and is only slightly narrower than the track slot to guide the device and roller along the track. The guide block is a separate member mounted on a metal hanger from the roller in one embodiment and is formed as an integral part of the hanger in a second embodiment.
