All RAD windshields and panels feature the absolute best ¼ inch thick polycarbonate available with ultimate clarity and the peace of mind that our product is 250 times more shatter resistant than safety glass. ALL our products have only the absolute best hard coated scratch resistant surface both inside and out. Every piece is completely hand assembled and fully ready for an effortless and tool-less install right out of the box. We pride ourselves in building the absolute best product right here in the USA. Our competition makes an inferior unfinished product leaving you to assemble and install.
