Sea-Dog Bus Bar with Cover – 4 Terminals (4266913)
A compact, high-current bus bar for DC or AC power distribution on your boat. Designed for positive or negative DC circuit distribution, or as an AC neutral or safety ground collection point, this single-bus block is rated for up to 300A and keeps all connections protected under a clear polycarbonate cover.
All four terminals are heavy-duty 5/16"-18 stainless steel studs — built for large-gauge cable and high-current feeds. The tin-plated copper bus and ABS housing resist corrosion in marine environments, and mounting hardware (four #8 flat-head fasteners) is included for a straightforward install.

Parts Desk Insights
Best use case: This is the go-to block when you need a dedicated high-current stud-only distribution point — think battery positive feeds, main engine grounds, or windlass and thruster circuits where you’re running heavy cable and don’t need screw-terminal branch circuits. The all-stud design keeps things simple and solid for high-vibration engine compartment installs. It’s a clean solution for consolidating two or three large feeds into one protected point without the bulk of a full distribution panel.
Need branch circuit screw terminals as well? Step up to the Sea-Dog Bus Bar with Cover – 6 Terminals (4266923), which adds six #10-32 screw terminals alongside two 5/16" studs. For the largest installs with two independent buses, see the Sea-Dog Dual Bus Bar with Cover – 12 Terminals (4266933).
