T-H Marine NBH31PDP Narrow Battery Holder Tray – Series 31
Install a Series 31 battery in tight spaces where a standard battery box won’t fit with the T-H Marine NBH31PDP Narrow Battery Holder Tray. Designed specifically for installations where width is limited — such as narrow bilge compartments, under-seat areas, and custom battery bays — this tray keeps your battery secure while taking up minimal horizontal space.
The tray features recessed mounting wells and recessed fasteners for a clean, low-profile installation with no protruding tabs to snag wiring or equipment. A poly strap with a quick-release buckle holds the battery firmly in place, and the chemical-resistant construction handles exposure to gasoline, oil, acid, and most other marine chemicals. Meets all NMMA specifications.

Parts Desk Insights
The NBH31PDP is the right choice when you need to fit a Series 31 battery — commonly used for house banks, trolling motors, and high-capacity electrical systems — into a space that’s too narrow for a standard battery box. The recessed fasteners and no-tab design make it a cleaner installation than most standard trays. If you want a stainless steel buckle for better corrosion resistance in saltwater environments, see the T-H Marine NBH31SSCDP Series 29/31 Tray with Stainless Steel Buckle.
