Sea Dog Line 54" Marine Battery Box Strap Kit
A longer-reach battery hold-down kit designed for larger battery group installations and battery boxes that require extra strap length to span the full width and secure properly. At 54", this strap accommodates Group 27, Group 29, Group 31, and other larger format batteries where a 38" strap would come up short.
The woven polypropylene strap resists UV fading and moisture absorption, and the injection-molded nylon buckle provides a lightweight, corrosion-free quick-release. Two mounting brackets and four #8 flathead fasteners are included for a complete, permanent installation without additional hardware.
What's Included
- 54" woven polypropylene strap
- Injection-molded nylon buckle
- Two mounting brackets
- Four #8 flathead fasteners
Best Use Case
The right choice for Group 27, 29, and 31 battery installations, dual-battery trays, or any application where a standard 38" strap doesn’t provide enough reach. Particularly useful on larger center consoles, cruisers, and offshore fishing boats running high-capacity house batteries. Also a practical replacement strap for larger battery boxes that have lost their original hold-down hardware.
