Stud insulator for marine high-amperage connections, the Blue Sea CableCap helps shield a single 0.50-inch stud on alternators, starters, windlasses, and other termination points.

Designed for stud-type connectors, this black CableCap provides an insulating cover for exposed high-amperage connection points. Its PVC construction supports use in marine electrical installations, while the 0.50-inch stud configuration matches the listed application. It accommodates cable sizes from 1 AWG through 2/0 AWG.

  • Insulates a single 0.50-inch stud to help cover exposed conductive connection points.
  • Made from PVC for a practical insulating barrier in marine electrical applications.
  • Fits stud-type connections on alternators, starters, windlasses, and other high-amperage devices.
  • Accommodates listed cable sizes from 1 AWG through 2/0 AWG.
  • Black color provides a clear, neutral finish for electrical installation layouts.
Use the CableCap wherever a stud-type connector requires insulation around a high-amperage termination point. It is suited to marine systems that include alternators, starters, windlasses, and similar electrical devices. The cover helps separate the conductive stud and connection area from accidental contact while keeping the installation organized. Its PVC construction and black finish make it appropriate for common boat electrical wiring and power-distribution work. Confirm the stud and cable configuration before installation, and use it as part of a properly prepared electrical system.
