Blue Sea Systems Cable Covers, Outlets & Thru-Deck Fittings

Blue Sea Systems Marine Cable Management Solutions

When routing cables through marine decks, bulkheads, and transoms, maintaining watertight integrity is non-negotiable. Blue Sea Systems' CableClam products provide a waterproof pass-through for antenna, transducer, and other cables without removal of the factory installed cable connector, solving one of the most common installation challenges in marine electrical systems.

The engineering advantage of Blue Sea Systems' approach becomes clear during installation and maintenance. These fittings save hours of time when removing or re-installing antenna and radar cable, as the connectors may remain intact after initial installation. This eliminates the frustration of cutting off expensive connectors, routing bare wire through traditional thru-hulls, and then re-terminating—a process that often leads to poor connections and signal degradation.

CableClam Product Range and Innovation

Blue Sea Systems offers their cable management fittings in multiple configurations to accommodate different installation scenarios and cable sizes. The updated product line includes the addition of five new models, including a side entry clam as well as versions with 316 stainless steel caps and pre-drilled rubber inserts. The traditional CableClams are available in connector openings ranging from 0.68 inches to 1.396 inches, while the innovative side entry design addresses installations where traditional top-mount fittings aren't practical.

Each fitting features pre-drilled and slit rubber seals for easier installation, constructed from UV-stabilized Buna-N rubber that resists degradation in harsh marine environments. The optional 316 stainless steel dress caps not only provide UV protection but also create a polished appearance that matches premium deck hardware. All fittings include corrosion-resistant stainless steel fasteners for long-term reliability above the waterline.

Applications Beyond Antenna Cables

While CableClams excel at antenna and radar installations, their versatility extends throughout the vessel. These cable covers, outlets, and thru-deck fittings are equally valuable for routing solar panel cables, transducer wiring, GPS antenna leads, and any other application where maintaining connector integrity matters. The waterproof seal prevents moisture intrusion that causes corrosion, while the robust thermoplastic ring protects cables from chafing at deck penetrations.
