Tired of replacing the entire upper roller shaft when only the rubber roller is worn out? This new shaft design will solve that issue. You will only need to purchase the shaft one time. The new shaft is a direct replacement for the older units, and fits all Benchmark ticket takers. The wear area is now 3 cast urethane O-rings that are easily replaced. The rings are sold in packs of 12 under part # KIT00078. Life expectancy on a set of O-rings is 1,000,000+ tickets!
