The dock floats we install are dependable flotation that can be easily applied to any new or existing dock system. These dock floats are foam-filled and are encapsulated in a .150" nominally thick shell that is made of virgin polyethylene with UV inhibitors. This tough shell helps prevent damage from the harsh sun and marine environment. The single-piece, rotationally-molded design eliminates seams that can result in separation and leakage. They are strategically designed with a flat top that includes molded-in mounting slots and holes for easy attachment to any framework.
