Stud CableCap insulator for marine high-amperage connections, helping protect a single exposed stud on alternators, starters, windlasses, and other electrical termination points.

This black CableCap fits a 0.47 to 0.13 stud configuration and covers stud-type connectors used in marine electrical systems. Its insulating design helps reduce the risk of accidental contact at exposed high-amperage connection points. Use it on compatible alternator, starter, windlass, and similar equipment terminals where a dedicated stud cover is required.

Insulates a single stud-type connector to help reduce accidental electrical contact.
Designed for alternators, starters, windlasses, and other high-amperage devices.
Black color supports quick visual identification among electrical components.
0.47 to 0.13 stud configuration helps match the cover to compatible connection hardware.
Compact connector accessory supports organized marine electrical installations.

Use the CableCap to cover an exposed stud on compatible marine electrical equipment. It’s suited to termination points on alternators, starters, windlasses, and other devices that use stud-type connections and carry high amperage. Covering the stud helps separate the connection from accidental contact while keeping the installation organized. Confirm the stud dimensions and available clearance before installation, especially when replacing an existing terminal cover. The black color makes the insulator easy to distinguish within a busbar, connector, or marine power-distribution system.
