Blue Sea 1002 Cable Clam 0.8"

The Blue Sea 1002 Cable Clam 0.8" is a marine-grade coaxial cable connector designed for anglers and boaters who demand reliability on the water. Whether you're installing a new antenna system, upgrading your VHF radio, or troubleshooting existing marine electronics, this weatherproof solution eliminates the need to disconnect and reconnect fragile coaxial fittings. Built by Blue Sea Systems—a trusted name in marine electrical components for decades—the Cable Clam allows you to make secure connections without removing factory connectors, protecting against corrosion, water intrusion, and the signal loss that comes from repeated connection cycles.

This 0.8-inch clamp mechanism uses a simple yet effective design: slip it over your existing coaxial cable and existing connector, tighten the fastener, and create a waterproof seal that keeps saltwater spray and moisture out of the signal path. The compact form factor (4 x 1 x 8 inches) and lightweight construction (0.2 lbs) make it easy to stow in your electronics toolkit or tackle box, with no special tools required for installation. The clam-style housing provides even pressure distribution across the connector joint, reducing the risk of intermittent connections that plague marine electronics in harsh environments.

Ideal for VHF antennas, marine GPS systems, and single-sideband radio installations, the Blue Sea 1002 Cable Clam works with standard 0.8-inch coaxial connectors commonly found on recreational and commercial vessels. Boat owners and fishing enthusiasts who operate in salt water or freshwater environments benefit most from this preventative maintenance tool, as it extends the service life of expensive radio and antenna systems by eliminating corrosion at connection points. Installation takes minutes with no specialized knowledge required—making it the smart choice for anyone seeking professional-grade marine electrical reliability.
