Parts Desk Insights
The BSS-2003 is most commonly used when a customer needs a single, dedicated high-current connection point — typically as a main positive or negative post near the battery bank, or as an additional distribution point when a busbar doesn’t fit the space. It’s also a popular choice for adding a dedicated feed post for a single large load like a windlass or thruster. Pair with the BSS-4004 Powerpost Insulator when mounting to a conductive surface or when additional insulation is required.
