The center vent screen is an amazing product!!! The attention to detail is amazing. Everything needed for the installation is included in the purchase. The installation is very easy and only takes about 30 minutes, including getting the tools out and putting them away when finished. The company has amazing customer service and is very quick to respond. I cannot say enough good things about this company or the product. If you are riding a shark nose I highly recommend you buy the vent screens!!!!
