Double-Flanged Wave Attenuator Hollow Bottom Shell

This double-flanged wave attenuator hollow bottom shell is made of virgin polyethylene with UV inhibitors and is .200" nominally thick. Simply drill a few larger holes in the sides to allow the shell to fill with water once it is submerged. The encased water will then act as the ballast for the wave attenuator or dock system.
