Blue Sea 4005 Standard CableCap - Small Pair

The Blue Sea 4005 Standard CableCap Small Pair is an essential marine electrical accessory designed to protect standard marine battery terminals and cable connectors from corrosion, moisture, and accidental short circuits. After years on the water, any serious boater or angler knows that saltwater and freshwater environments wreak havoc on exposed battery connections—corroded terminals mean dead batteries when you need them most, missed fishing windows, and safety risks in rough conditions.

These cable caps solve that problem by providing a simple, reliable barrier between your battery posts and the elements. Built by Blue Sea Systems, a trusted name in marine electrical safety for decades, the 4005 Standard CableCap features a durable, weather-resistant design that fits snugly over standard marine battery terminal connectors. The small pair configuration is engineered for tighter spaces or smaller battery banks common in center consoles, bass boats, and cruising sailboats where every inch of deck space matters.

Anglers and boaters who maintain their own systems benefit most from this pair—installation takes seconds and requires no tools or electrical knowledge. Simply slide the caps over your battery terminals after disconnecting shore power or before extended storage periods. The caps resist UV degradation and won't crack or become brittle in the harsh marine environment, maintaining a secure fit year-round whether you're navigating coastal waters or inland lakes.
