Purchased to replace superatv poly flip up. No installation instructions included, however instal is very easy. I removed the 3 front roof clamps, pushed the roof up, and added some of the shipping foam that is formed to the windshield edge. There was room for my wiper motor, but I had to remove the rear view mirror to instal motor, should have installed before mounting windshield. Works well with side by side.com doors, fit and finish are great, quick shipping from Idaho to Pennsylvania , 7 days. Reduced field of view slightly , but also reduced air into cab significantly. l talked with the company owner, told me he has more RMax products in work, rear window, heater, and winter radiator block off plate .I will not hesitate to purchase more quality items from Inner Demon. Thank you for a great product.
