Changing water levels Floating dock adjusts to fluctuating water conditions - the unique design of the float chambers trap air on the surface of the water for additional buoyancy. As the water levels change the dock raises and lowers. Easy Installation Connect-A-Dock floating dock systems are versatile - the modules can be configured end to end or side to side, as long and wide as you wish and for many different applications or configurations on water or land. Its 5 minute (per module) attachment system means easy installation and the rotationally molded polyethylene construction ensures many years of dependable service.
