HLTIT Metal Battery Mounting Tray for Group 31/34/35 — Fits 10.63×7.06×7.5 in, Rust-Resistant Steel, Bolt-In

HLTIT's metal battery mounting tray secures most Group 31/34/35 batteries up to 10.63"×7.06"×7.5" with rust-resistant steel, adjustable hold-down hardware, and pre-drilled bolt-in mounting.

Whether you’re replacing a worn battery holder or fitting a new auxiliary battery in a truck, boat, RV, or trailer, this steel tray is engineered to simplify installation and protect the battery from vibration, moisture, and corrosion. Built from coated steel with ventilation holes and supplied J-bolts, washers, and nylock nuts, the tray provides a reliable foundation for single-battery applications in automotive and marine environments.

How does this tray adapt to different battery sizes?

The tray accepts batteries up to the specified external dimensions and uses adjustable hold-down hardware to clamp the battery firmly in place. The included angle bar and adjustable J-bolts let you customize fit for Group 31, 34, 35 and other similarly sized batteries without aftermarket fabrication.

• Accommodates batteries up to 10.63" L × 7.06" W × 7.5" H
• Adjustable angle hold-down with zinc-plated J-bolts
• Works with Group 31/34/35 types and comparable sizes

Is installation difficult for vehicles, boats, or RVs?

Installation is straightforward: the tray comes with pre-drilled mounting holes and the necessary hold-down hardware so you can bolt it into place quickly. Typical installs require basic hand tools and a few mounting fasteners to secure the tray to a floor, bracket, or vehicle frame.

• Pre-drilled holes for fast, repeatable mounting
• Includes hold-down angle bar, J-bolts, washers and nylock nuts
• Compatible with bolt-in mounting to floors, sills, or custom brackets

How does the tray protect the battery from the elements and vibration?

The tray’s steel construction resists impacts and reduces movement under load, while the anti-corrosion finish helps prevent surface rust in damp environments. Strategically placed round holes promote airflow and drain water, helping the battery stay cooler and reducing moisture buildup that can accelerate corrosion.

• Coated steel resists rust and maintains structural strength
• Ventilation/drain holes assist thermal management and water runoff
• Robust design minimizes vibration and movement under load

What tools or parts will I still need after purchase?

The tray ships with core hold-down components, but you may need vehicle-specific bolts or anchor hardware depending on your mounting surface. Bring common hand tools and the correct-length fasteners for your chassis or mounting location.

• Included: angle hold-down bar, zinc-plated J-bolts, washers, nylock nuts
• Recommended: drill, wrench set, and vehicle-appropriate mounting bolts
• Optional: rubber pads or insulating mat to reduce vibration further

Who this is for: technicians, DIYers, and fleet owners who need a reliable, corrosion-resistant battery mounting solution for cars, trucks, boats, RVs, pickup beds, and trailers. If you want a bolt-in steel tray that fits common large battery groups, simplifies hardware selection, and improves ventilation and drainage compared with plastic holders, this HLTIT tray offers a durable, serviceable option.
