Ease of Installation
Great product. Came with all the necessary parts and everything was in great shape. I mounted it on a jeep tj two piece hard top. Really Looks good, and no wind noise. Just be careful when measuring for the holes. The back holes were a little tight so I added an eighth of an inch to the front and perfect fit. If you need some cross bars mounted permanently this is the product. Really looks and works great.
