Blue Sea CableClam w/Stainless Steel Dress Cap - 0.83"

The Blue Sea CableClam with Stainless Steel Dress Cap (0.83") is a marine-grade cable penetration fitting designed to seal above-waterline openings while maintaining a professional deck appearance. Built by Blue Sea Systems—a brand trusted across recreational and commercial vessels—this cable clamp manages cable runs through cabin bulkheads, helm stations, and transom installations where water ingress must be prevented and hardware visibility controlled.

The 0.83-inch connector diameter accommodates standard marine electrical connectors and D-sub connector sizes common in navigation, autopilot, and sensor installations. Pre-drilled and slit rubber seals simplify installation—no need to custom-cut gaskets—while stainless steel fasteners resist saltwater corrosion that degrades standard hardware over seasons of exposure. The polished stainless steel dress cap conceals mounting fasteners and cable routing, protecting against UV degradation and providing visual consistency with other deck hardware. Maximum cable diameter rating of 0.44 inches ensures proper compression without over-tightening, which can damage cable jackets and compromise electrical integrity.

This fitting is rated for above-waterline use only, making it ideal for helm console wiring, through-cabin power distribution, instrument clusters, and trim-tab control lines. Weekend anglers installing fish-finder transducers or autopilot systems, and serious offshore operators running redundant navigation networks, rely on Blue Sea cable management to keep electrical connections dry and protected. The stainless construction stands up to spray, rain, and humidity without corrosion concerns that plague painted or zinc-plated alternatives.
