Abstract:
A guide assembly for use in an overhead door mounted in a door opening, the guide assembly comprising:a bracket for being carried by the door;a pin mounted in the bracket, the pin having a first end and a second end; the first end of the pin including a tip made from a low-friction material subject to observable wear at a predictable rate for indicating the degree of material worn away, the pin adapted to be positioned so that its first end extends beyond the bracket and slides in and frictionally-engages a channel carried in the door opening within which the overhead door is mounted for movement, and further wherein the low-friction material includes an outer layer of a material having a first color and an inner layer of material having a second color that is different from the color of the outer layer of low-friction material, wherein wearing away of the outer layer of low-friction material exposes the inner layer of low-friction material to provide a visual indicator of wear of the tip.
