Sea-Dog Bus Bar with Cover – 6 Terminals (4266923)
A heavy-duty single bus bar for DC or AC power distribution on your boat. Use it for positive or negative DC circuit distribution, or as an AC neutral or safety ground collection point — all in a compact, covered block rated for up to 300A. The clear polycarbonate cover protects connections from accidental contact and moisture, while the tin-plated copper bus and ABS housing resist corrosion in demanding marine environments.
Two 5/16"-18 stainless steel stud terminals handle your main feed connections, and six #10-32 stainless steel screw terminals provide branch circuit hookups — eight connection points total. Mounting hardware (four #8 flat-head fasteners) is included.

Parts Desk Insights
Best use case: This is the right choice when you need a single high-current distribution point — the 300A rating makes it well-suited for main positive or negative feeds on larger outboard or inboard installations. The 5/16" stud terminals accept heavy gauge cable comfortably, and the six screw terminals are enough for most single-bank distribution needs without the bulk of a larger block. A popular pick for engine compartment grounds, battery negative distribution, or AC panel neutral bars.
Need more terminals? The Sea-Dog Dual Bus Bar with Cover – 12 Terminals (4266933) gives you two independent buses in one unit. For lighter-duty or tighter-space installs, the Sea-Dog Bus Bar with Cover – 4 Terminals (4266913) is a compact alternative.
