The Dock Blocks system uses a patented 4-pin technology, which doubles the connection points for increased stability and a superior experience. Our docks feel sturdy underfoot and our unique formulation of HDPE material won’t get spongy or soft like other docking systems. When you choose Dock Blocks, you can expect a safe and strong platform for all your docking needs – whether that’s an extra wide walkway to get your family on and off the boat or a higher end experience for your yacht club or marina members.
