I had a pair of these on two large fenders we use when rafting our pontoon to our wakeboard boat. I liked them so well, that I bougt 4 more for the regular sized fenders we use when rafting our toon to other boats. The straps fit easily around square or round railings and can be easily placed where ever we need them, even in tight spaces between the railings and furniture on our toon. I like the easy height adjustment as well, and they seem to work well even when subjected to wave action from other passing craft.
