Dock Floats

PermaFloat dock floats give you dependable flotation for any new or existing dock. Each float is foam-filled and sealed in a .150" nominal shell of virgin polyethylene with UV inhibitors, so it stands up to sun and water. The single-piece, rotationally molded design has no seams to split or leak, and the flat top has molded-in mounting slots and holes for easy attachment to your frame.
