Ace foam-filled float drums offer durable flotation for a variety of dock systems. The plastic, one-piece, seamless exterior shell prevents leakage and separation caused by weak joints. The drum wall is made of tough virgin polyethylene with ultra violet inhibitors to prevent damage from the sun, debris, oil, gas, marine organisms, salt and fresh water. A nominal wall thickness of .150” (and a minimum thickness of .125”) offers a stronger, more durable float. The top of the shell is flat with molded-in mounting slots for easy attachment to any dock frame. The interior of the float drum is filled with expanded polystyrene (EPS) foam. The foam is steam-pressured for a tight fit to provide the highest reserve buoyancy possible.


Ace offers rotationally molded floats with over 70 sizes available. You are sure to find an Ace float drum that fits your needs, whether you are a private dock builder or a contractor for a large marina complex.
