Attwood Heavy-Duty Group 27 Battery Tray
Built for demanding marine environments, this heavy-duty battery tray secures your Group 27 battery with a rigid, corrosion-resistant design that goes beyond a basic strap-and-buckle setup. The non-corrosive black plastic construction resists moisture, fuel, and bilge exposure, while the adjustable-height crossbar and stainless steel retaining bolts clamp the battery firmly in place — even in rough water conditions.
Meets ABYC Standard E-10 and U.S. Coast Guard requirements, making it a compliant choice for inspected vessels and charter boats. Installs with standard #10 fasteners.
Key Features
- Heavy-duty non-corrosive black plastic construction

- Meets ABYC Standard E-10 and U.S. Coast Guard requirements
- Installs with #10 fasteners (not included)

Best Use Case
The ideal choice for boaters who need a compliant, heavy-duty hold-down solution — particularly on inspected vessels, charter boats, or any application where a simple strap-and-buckle tray isn't sufficient. The stainless steel crossbar system provides a more positive lock than polypropylene strap designs, making it well-suited for high-vibration installations such as outboard-powered center consoles and offshore fishing boats.
