This windshield is made from 3/16” Thick Hard-Coated Polycarbonate making it virtually unbreakable under normal use. Unlike others, on the market, the Hard-Coating is on both sides. The Aluminum top stiffener seals along the top and remains in place as a visor when the windshield is removed. The Tool-Less removable allows you to remove it in minutes on a hot day or to clean it. Combine it with the Aluminum top P/N 13522 and Cab Back P/N 13524 for added protection from the rain, snow and mud.
