The most important thing that sets the ANC corner wheels apart from the "others" is the fact that their patented design does not have a valve to allow air to escape and the ANC corner wheels are designed with "tubes" molded into the wheel which provides substantially more protection for you beautiful boat from the dock. The competition's dock wheels may look full of air when you come into your dock, only you find out the hard way that they're actually "flat."
As boats have become beamier and beamier, it's harder to get into marina slips. These wheels are great! You can just roll your way into your slip. Compliment the "Corner" wheels with the "Side Mount" wheels and you've made an excellent system to protect your yacht. If you have a larger boat or a "crosswind" situation, the double corner wheel offers even more protection by spreading the load to a great surface area. Compare the costs of repairing gel coat against buying the best ... the Astro corner wheels.
The rings of holes around our dock wheels offer much more protection and cushion than a single wall dock wheel.
Astro dock wheels come in 10" and 14" sizes, are available in corner bracket or straight bracket. Double corner wheels are available in 10" and 14" sizes for larger boats or where severe cross wind situations exist. All corner wheels have heavy steel brackets that are hot dipped galvanized.
