A strip of PTFE coated fiberglass fabric — available in .005" or .010" thickness — applied to one or both belt edges. Can be placed on the top side, or top and bottom, and affixed by heat seal, stitching, or both.
Edge treatment protects against wear, abrasion, and unraveling at the belt edge. It also provides a reinforced surface that supports belt driving and tracking options. Edging is natural brown in color.
