attwood Marine Battery Tray for Group 27 — USCG & ABYC Compliant, 12" L × 6-7/8" W with Stainless Adjustable Hold-Down

The Attwood 9095-5 is a USCG- and ABYC-compliant heavy-duty battery tray designed to securely mount Group 27 and 27M marine batteries with an adjustable stainless-steel hold-down for long-term corrosion resistance.

Built from non-corrosive black plastic and engineered for the rigors of the marine environment, this tray keeps a 12" × 6-7/8" battery firmly in place while meeting U.S. Coast Guard and ABYC Standard E-10 requirements. The adjustable crossbar with stainless retaining fasteners lets you tighten the hold for a snug, vibration-resistant fit. Installation is straightforward using #10 fasteners (not included), so you can replace or upgrade battery mounts without complex tools or fabrication.

How does this tray protect batteries on rough water?

The Attwood 9095-5 secures the battery with a heavy-duty molded base and an adjustable hold-down crossbar that resists movement and minimizes vibration. Its corrosion-resistant materials maintain strength in saltwater and humid conditions, reducing the risk of mounting failure over time.

• Durable, non-corrosive black plastic construction
• Adjustable-height crossbar for tight, customized clamping
• Stainless-steel retaining fasteners resist rust in marine environments
• Designed to reduce vibration and lateral battery movement

Will it fit my battery and meet marine safety rules?

This model is sized specifically for Group 27 and 27M batteries with inside dimensions of 12" long by 6-7/8" wide, and it’s manufactured to comply with U.S. Coast Guard and ABYC E-10 standards. That compliance simplifies inspections and helps ensure your battery installation follows accepted marine safety practices.

• Fits Group 27 / 27M batteries (12" × 6-7/8" internal dimensions)
• USCG-approved for marine battery installations
• ABYC Standard E-10 compliance for accepted electrical and battery mounting guidance
• Simplifies meeting regulatory checks during marine inspections

How easy is it to install and maintain?

Installation requires basic hand tools and #10 fasteners (not included); the tray mounts quickly to most battery compartments and stringers. Maintenance is minimal—periodic checks of the stainless fasteners and the hold-down tension are usually sufficient to keep the battery secure and corrosion-free.

• Mounts with standard #10 screws for quick installation
• Minimal upkeep: inspect fasteners and clamp tension periodically
• Molded plastic resists moisture, simplifying cleaning and care
• Replacement or repositioning is straightforward if needed

What hardware and accessories should I use with it?

Use #10 marine-grade fasteners and stainless hardware for the best long-term performance; avoid mixing metals that could create corrosion. If your battery compartment requires additional securing, pair the tray with approved hold-down straps or insulated terminal covers to keep connections safe and tidy.

• Use #10 stainless or marine-rated screws for mounting
• Stainless retaining fasteners included to secure the crossbar
• Optional: marine battery straps or insulated terminal covers for added safety
• Avoid incompatible metals to reduce galvanic corrosion risk

Who is this for: The Attwood 9095-5 is aimed at boat owners, fleet managers, and marine technicians who need a reliable, regulation-compliant mounting solution for Group 27 and 27M batteries. It’s ideal for recreational and light commercial vessels that require durable, low-maintenance battery supports that meet USCG and ABYC installation expectations.
