T-H Marine Narrow Battery Tray NBH-31P, 29/31 Series, Poly Strap

The T-H Marine NBH-31P is a narrow battery tray built for boats and other tight-space installations where a standard-width battery box will not fit. Sized for Group 29/31 series batteries, this space-saving tray uses the smallest possible footprint to solve tight-space mounting problems without sacrificing a secure hold. The tray mounts with recessed mounting wells and recessed fasteners, so there are no exposed tabs or snag points once installed, giving a clean, low-profile finish.

A poly strap with a strong quick-release buckle holds the battery firmly in place while still allowing fast access for battery swaps or maintenance. The tray body is molded from a chemical-resistant material that stands up to gasoline, oil, acid, and most other chemicals commonly found in a boat's battery compartment, making it suitable for long-term marine use. The NBH-31P meets NMMA specifications and is USCG and ABYC compliant, so it satisfies the safety and construction standards boat builders and installers look for in battery storage hardware. For installations that call for a different retention method, T-H Marine also offers a stainless steel rod-style strap option as a separate product in its Rod Style Tray line.
