The Premier Fleet Wear Gauge Set is the perfect tool for judging the useful life of couplings, pintle hitches, and drawbar eyes. This easy-to-use gauge set is a must for maintenance managers and safety personnel. The latch gauge bar measures the gap space between the coupling hook's top and the latch plate's bottom. This allows you to quickly and accurately determine the wear on the coupling and whether it needs replacing. The set also includes a drawbar eye gauge to measure the wear on the drawbar eye.
