Drives® suggested the EZ Chain Wear Gauge®, an easy-to-use method for testing chains for elongation in any application. The EZ Chain Wear Gauge quickly detects chain elongation at 3 percent, the limit at which the chain should be replaced to prevent costlier damage to the application’s sprockets. Used in conjunction with our Chain Wear Measurement tracking tool accessed via Chain-Engineer.com, the pair can help users extend the life of all their equipment.
