Blue Sea 2723 DualBus Plus 5/16" Stud - 5 x 10 - 32 Screw Terminal

The Blue Sea Systems 2723 DualBus Plus 5/16" Stud is a dual-purpose bus block designed for marine electrical systems where space and circuit organization demand a compact, code-compliant solution. This 5 x 10 configuration combines negative and positive distribution on a single block, eliminating the need for separate components and streamlining your boat's electrical backbone. The 32 screw terminals provide secure, redundant connection points for battery banks, charging systems, and loads—critical in marine applications where vibration, salt spray, and thermal cycling can degrade connections over time.

Constructed to meet Coast Guard and ABYC (American Boat and Yacht Council) standards, the 2723 includes a clear polycarbonate cover that snaps firmly into place, meeting mandatory insulation requirements for marine installations. The 5/16" stud design accommodates standard battery cable lugs and distributes current across multiple terminals without concentrated hot spots. The compact 4 x 2 x 8 inch footprint fits tight engine compartments and below-deck electrical panels typical of cruising sailboats and offshore fishing vessels. Stainless hardware resists corrosion in salt-air environments—a practical necessity for anyone operating beyond protected waters.

This block serves both weekend fishermen upgrading auxiliary power systems and serious offshore anglers building redundant electrical architecture. It's the standard choice for dual-battery setups, auxiliary charging circuits, and split-load management in mid-sized cruising boats and center consoles. Buy the Blue Sea 2723 DualBus Plus when code compliance, reliability, and proven marine-grade construction matter more than cutting corners on your vessel's electrical infrastructure.
