The Open Trail full windshield is made with ultra durable 0.177" Makrolon® Polycarbonate for long lasting, high strength protection and a clear view of the trail. This windshield works with the Open Trail roof as well as the OEM roof. The windshield has a seal at the bottom that rests against your vehicle. It is attached to your roll bars using six galvanized steel, rubber coated P clamps that are bolted to the windshield through pre-drilled holes.
