attwood Battery Tray for 29/31 Series Batteries — Black, Heavy-Duty Plastic with Stainless Retaining Bolts

The Attwood 9094-5 is a heavy-duty, non-corrosive battery tray designed to securely mount 29/31 Series marine batteries with an adjustable crossbar and stainless steel retaining bolts.

This compact, USA-made battery tray gives boaters a durable mounting platform that resists saltwater corrosion and meets marine safety standards. Built from high-strength injection-molded plastic and paired with stainless hardware, the tray holds 29/31 Series batteries snugly while fitting standard #10 fastener installations. It was engineered to comply with ABYC E-10 and USCG requirements so you can install it with confidence aboard small craft, workboats, or leisure vessels.

How does this tray secure a 29/31 Series battery?

The tray secures batteries using an adjustable-height crossbar and stainless steel retaining bolts that clamp the battery in place to minimize movement during rough conditions. Its internal footprint matches common 29/31 battery profiles so the battery sits flat and centered.

• Adjustable crossbar allows vertical clamping for different battery heights
• Stainless steel bolts resist corrosion and keep a positive hold
• Interior dimensions 13 1/6" x 6 7/8" match F29/31 battery sizes
• Mounts with #10 fasteners for a secure deck or compartment attachment

Is this tray durable in marine environments?

Yes—the tray is molded from heavy-duty, hi-strength plastic formulated to withstand UV exposure and saltwater without corroding. The stainless hardware and non-reactive plastic combine to provide long-term resistance to the elements and typical boat vibration.

• Heavy-duty injection-molded plastic resists cracking and deformation
• Non-corrosive stainless steel retaining bolts extend service life
• Designed and manufactured in the USA with marine-grade materials

How simple is installation and what are the size and mounting requirements?

Installation is straightforward: place the tray, fasten it with #10 screws, adjust the crossbar, and tighten the stainless bolts. The compact footprint and standard fastener requirement make it compatible with most battery compartments and retrofit projects.

• Inside dimensions: 13 1/6" long x 6 7/8" wide
• Uses readily available #10 fasteners for deck or bulkhead mounting
• Crossbar adjusts to secure batteries of varying heights within the 29/31 form factor

Does it meet marine safety and regulatory standards?

The Attwood 9094-5 was designed to satisfy common U.S. marine safety benchmarks, including ABYC Standard E-10 and USCG requirements, which address secure battery mounting and containment. Selecting a tray built to these standards helps meet inspection and safety expectations for recreational and commercial vessels.

• Meets ABYC E-10 recommendations for battery installation
• Complies with applicable USCG mounting and retention criteria
• Installed correctly, it helps reduce the risk of battery displacement and related hazards

Who is this for: The Attwood 9094-5 is aimed at boat owners, marine technicians, and DIY hobbyists who need a dependable, corrosion-resistant mounting solution for F29/F31 style batteries. It’s ideal for small boats, workboats, and anyone replacing worn trays or upgrading battery retention to meet ABYC/USCG standards.
