CamcoGroup 27 / 30 / 31Coast Guard CompliantCamco 55404 Large Battery Hold-Down Tray

Keep your RV, marine, or automotive battery locked in place with the Camco 55404 Large Battery Hold-Down Tray. Built from heavy-duty acid-resistant plastic with stainless steel hardware, this tray meets U.S. Coast Guard and ABYC standards and includes everything you need to secure your battery right out of the box.

A Secure, Compliant Battery Mount for RV and Marine Use

Loose batteries are a safety hazard -- they can tip, spill electrolyte, and cause electrical shorts. The Camco 55404 tray holds Group 27, 30, and 31 batteries firmly using a cross-bar and rod system with hand-tighten knobs, so there are no tools required after initial mounting. The solid leakproof bottom contains any electrolyte that escapes, protecting your battery compartment from corrosive acid damage.

Designed to meet U.S. Coast Guard CFR 183.420 and ABYC E-10.7 specifications, this tray is a compliant choice for boats, pontoons, and marine vessels as well as Class A, B, and C motorhomes, fifth wheels, travel trailers, and cargo vans. The included stainless steel hardware resists corrosion in wet or humid environments.

Fits Group 27, 30, and 31

Accommodates the most common large-format RV and marine battery sizes. Max battery size: 12-11/16 in. L x 6-3/4 in. W x 8-3/4 in. H.

Acid-Resistant Construction

Heavy-duty plastic shell resists battery acid and electrolyte. Solid leakproof bottom keeps spills contained and protects surrounding surfaces.

Stainless Steel Hardware

Included rods, cross bar, and knobs are stainless steel for long-term corrosion resistance in marine and outdoor RV environments.

Regulatory Compliance

Meets U.S. Coast Guard CFR 183.420 and ABYC E-10.7 specifications, making it a compliant solution for federally regulated marine applications.

Complete Kit -- No Extra Hardware Needed

The 55404 ships with everything required: one tray, two stainless steel rods, one cross bar, and two hand-tighten knobs. No additional hold-down hardware to source separately.

Battery Size Reference

This tray is sized for large-format batteries. Confirm your battery's dimensions before ordering:
- Group 27: approximately 12-1/2 in. L x 6-3/4 in. W x 8-15/16 in. H
- Group 30: approximately 11-9/16 in. L x 6-13/16 in. W x 7-7/16 in. H
- Group 31: approximately 12-11/16 in. L x 6-13/16 in. W x 9-7/16 in. H
Maximum battery dimensions the tray will accept: 12-11/16 in. L x 6-3/4 in. W x 8-3/4 in. H.

Not Designed for AGM or Lithium Batteries Larger Than the Listed Max Size

Verify your battery's actual case dimensions against the tray's maximum capacity. Some AGM and lithium group batteries have non-standard case sizes that may exceed 12-11/16 in. length or 6-3/4 in. width and will not fit securely in this tray.

Installation and Maintenance Tips
  • Mount the tray to a flat, solid surface using fasteners appropriate for the substrate (fasteners not included for base mounting).
  • Periodically inspect the stainless rods and knobs for tightness, especially after rough road travel or extended marine use.
  • Rinse the tray interior if electrolyte accumulates to prevent long-term plastic degradation.
  • Check battery terminal connections and hold-down tension at the start of each season.

Important Information
  • Maximum battery case size is 12-11/16 in. L x 6-3/4 in. W x 8-3/4 in. H -- batteries exceeding these dimensions will not be properly secured.
  • Base mounting fasteners (to secure tray to the vehicle or vessel surface) are NOT included; use fasteners rated for your installation substrate.
  • This tray is designed for standard lead-acid, AGM, and gel batteries within the listed group sizes. Verify case dimensions for non-standard or lithium battery packs before purchase.
  • Inspect hold-down hardware and tray for cracks, corrosion, or loosening before each trip. A damaged tray may not contain electrolyte or prevent battery movement.
  • Do not exceed the battery size limits; an oversized battery may damage the tray or fail to be held securely, creating a safety risk.
