Utilizing three chemically bonded layers, the KS03 is designed for use in environments where a harder polyurethane surface is needed. The KS03 has a softer 70A durometer sandwiched between two hard 93A durometer pieces of polyurethane. This allows you to have an extremely tough scraping surface, yet maintain flexibility. This unique design also allows you to turn the wiper around when worn, giving you the longest wear life of any belt scraper on the market. KS03 is available in thicknesses ranging from 1" to 2".
