Attwood 9091-5 Adjustable Battery Tray for Group 27/27M Marine Batteries

The Attwood 9091-5 is an adjustable battery tray built to keep Group 27 and 27M marine batteries securely mounted through rough water, vibration, and trailering. Molded from durable, non-corrosive black plastic, the tray resists the moisture and salt exposure common in onboard electrical compartments while providing a rigid base that keeps the battery from shifting during operation. An adjustable-height crossbar combines with two retaining bolts to clamp the battery down firmly, and the tray is sized specifically to cradle Group 27 and 27M battery cases for a snug, vibration-resistant fit.

Installation is straightforward: the tray mounts using number 10 screws, making it a quick swap for boats, RVs, and other 12-volt battery installations. The design meets ABYC standard E-10 and U.S. Coast Guard requirements, so it satisfies the electrical safety standards marine installers and inspectors look for. Whether replacing a cracked or corroded tray or adding secure battery mounting to a new setup, the Attwood 9091-5 delivers a dependable, code-compliant hold-down solution for Group 27/27M batteries.
