Attwood 9084-1 Large Vented Battery Box with Mounting Strap, Fits Group 29 and 31 Batteries

The Attwood 9084-1 is a large vented battery box built to hold and protect Group 29 and Group 31 series marine batteries up to 9-3/4 inches in height. Molded from acid-resistant polypropylene, the box is impact-tested from -20 F to +120 F, so it holds up to harsh marine and RV environments year-round. The vented lid design includes cable openings and upward-facing vents that release battery gases while helping to minimize water intrusion, protecting both the battery and the surrounding equipment. A heavy-duty 40-inch hold-down strap is rated to withstand 350 pounds of force, nearly four times the U.S. Coast Guard requirement, keeping the battery securely in place even in rough conditions. The box meets ABYC Standard E-10 and USCG Specification 183.420, making it suitable for both OEM and aftermarket installations. Large rolled-edge handles make the box easy to carry, molded-in instructions provide quick reference during installation, and mounting hardware is included for a fast setup. Inside dimensions measure 15-7/16 inches long by 6-15/16 inches wide by 9-3/4 inches high, with outside dimensions of 18-7/8 inches long by 9-1/4 inches wide by 10-1/4 inches high. The box is finished in black.
