ABSTRACT:
Chain elongation indicator and method for use with a chain having a first link reference point on a first link and a second link reference point on a second link. The indicator includes an indicator body having first and second indicator reference points, such that the distance between said first and second indicator reference points corresponds to a predetermined percentage distance between first and second link reference points of a non-elongated chain. The first indicator reference point is aligned with the first link reference point on the first link of the chain, and the second link reference point is aligned with the second link reference point on the second link of the chain, so that the distance between the first link reference point and the second link reference point may be observed.
