Hardliner-brand Classifier Shoes feature a tapered design which provides more wear-resistant urethane along the outer edge of the shoe resulting in extended wear life. Longer shoe life means less maintenance downtime and lower operating costs. Light-weight Hardliner Classifier Shoes are both abrasion- and corrosion-resistant for extended life. Hardliner urethane material will remain flexible and operate safely over a wide (sub-zero to +180°F) temperature range. Sizes are available to match many O.E.M. classifier tank systems.
