Generic Battery Mounting Tray Bolt-In — Fits up to 10.63"×7.06"×7.5" — Corrosion-Resistant, Ventilated

This is an adjustable, bolt-in steel battery mounting tray that secures batteries up to 10.63" L × 7.06" W × 7.5" H with corrosion-resistant finish and ventilation.

Built from welded carbon-steel plates with a flame-retardant protective coating, this bolt-on battery box tray gives a rigid, ventilated platform for automotive, marine and RV batteries. The kit arrives with base plates, hold-down bar, zinc-plated J-bolts, T-bolts and a full set of nuts and washers so you can fasten a battery without welding or custom fabrication. The perforated base improves airflow and drainage while the adjustable bolt pattern accommodates many common battery sizes.

How does this tray keep a battery stable during travel?

The tray uses interlocking steel plates and an adjustable hold-down bar that clamp the battery firmly to the mounting surface. Multiple bolt positions let you lock the battery in place so it won’t shift under vibration or while cornering.

• Four steel base plates form a rigid platform.
• Hold-down angle and long bolts secure the top of the battery.
• Zinc-plated J-bolts and T-bolts provide strong threaded fastening.
• Wide support surface spreads load across the tray to avoid point-stress.

Will it resist rust and work in wet or salty environments?

The tray surface receives a flame-retardant plastic spray that significantly reduces oxidation and corrosion compared with raw steel. Zinc-plated hardware further protects fasteners in marine and outdoor settings, extending usable life in damp conditions.

• Plastic-coated steel surface for rust resistance.
• Zinc-plated J-bolts and corrosion-resistant nuts included.
• Perforated base allows water to drain and air to circulate.

How adjustable is the fit for different batteries?

Designed with adjustable bolts and multiple mounting holes, the tray holds batteries up to 10.63" long, 7.06" wide and 7.5" tall. You can reposition the plates and choose different bolt hole patterns to cradle slightly smaller or larger battery footprints within the stated limits.

• Fits batteries up to 10.63" L × 7.06" W × 7.5" H.
• Adjustable bolt locations let you center the battery for best balance.
• Includes a full fastener set for flexible configurations.

How simple is installation for DIY projects?

Installation is a bolt-in process—no welding or special tools required—so it's suitable for DIY upgrades and field repairs. The kit contains all necessary plates, T-bolts, washers and nuts; follow a few straightforward steps to build the tray and clamp the battery in place.

• Step-by-step assembly with four base plates and matching bolts.
• Threaded fasteners allow easy tightening and later removal.
• Compact kit fits into RVs, boats, camper builds and vehicle mods.

Who is this for? Installers, DIYers and modifiers who need a tough, ventilated battery platform for boats, RVs, camper conversions, custom vehicle projects or off-grid cabins will benefit from this tray. It’s aimed at users wanting a rust-resistant, easy-to-install bolt-on solution that gives firm mechanical support without fabricating a custom box.
