If you're building, repairing, or upgrading a floating dock, the foundation is everything. You need flotation that is reliable, durable, and engineered to last. That's why we are proud to offer Hendren Plastics Eagle Float Drums, the gold standard in dock flotation.
Manufactured in the USA by Hendren Plastics, Eagle Floats are trusted by dock builders and waterfront owners across the country. They exceed all Marine Industry standards for encapsulated dock flotation, giving you peace of mind for years to come.
Key Features That Set Eagle Floats Apart
Superior Construction & Durability
One-Piece Seamless Shell: Utilizing a high-tech rotational molding process, each float drum is constructed as a single, seamless piece of virgin-grade polyethylene. This eliminates weak points that can lead to leaks and separation.
.150" Nominal Wall Thickness: The robust, extra-thick shell is designed to withstand harsh marine environments, including resistance to saltwater, oil, gas, and fuels.
Built to Resist Wildlife: The tough polyethylene shell prevents the polystyrene core from degrading the environment and is specifically designed to resist damage from aquatic wildlife such as muskrats, otters, and beavers.
UV Protection: Integrated ultraviolet (UV) inhibitors guard the shell against sun damage, ensuring long-term color and structural integrity.
Maximum Flotation & Cutting-Edge Technology
Solid EPS Foam-Filled Core: The interior is filled with a precision-cut Closed Cell Expanded Polystyrene (EPS)foam core. This solid core ensures dependable buoyancy and guarantees that the float is impervious to sinking, even if the outer shell is compromised.
Computer-Controlled Foaming: Hendren Plastics utilizes a proprietary, state-of-the-art manufacturing process involving Infrared telemetry and computer-controlled steaming. This technology ensures every single Eagle Float is consistently and precisely foamed, resulting in the most reliable and dependable foam core in the industry.
Tank-Tested Buoyancy: All Eagle Float drums are rigorously tank-tested to provide customers with accurate, reliable buoyancy ratings for precise dock design and calculations.
Regulatory Compliance and Warranty
Meets Industry Standards: Eagle Floats are engineered to meet or exceed all U.S. Army Corps of Engineers regulations and similar standards for encapsulated dock flotation, including surpassing Falling Dart and Hunt Absorption Standards.
Industry-Leading Warranty: We stand behind the quality. Eagle Float drums are protected by an exceptional 15-Year Limited Manufacturer Warranty against manufacturing defects, effective to the original owner.
Easy Installation
Molded-In Mounting Slots: The flat top surface features convenient, molded-in mounting slots (usually around ten slot locations on the flange) for secure and easy attachment to any dock framework—whether it's wood, aluminum, or steel.
Versatile Attachment Profiles: Available in both Standard (molded-in slots) and Heavy Duty Flange Attachment profiles to suit your specific construction and hardware needs.
