At SEANAV, we understand that clear and reliable communication is essential at sea. That’s why we supply and support the SAILOR Thrane & Thrane Spiral Cord for Intelligent Handset C4901—a durable, marine-rated cable designed to maintain strong audio connections between the handset and your communication system.

This coiled cord connects to the SAILOR C4901 handset, widely used in maritime GMDSS setups, bridge communications, and internal ship systems. A damaged or frayed spiral cord can compromise safety by interrupting voice transmission. Replacing it promptly ensures consistent and clear ship-to-ship or ship-to-shore communication.
We stock genuine spiral cords that match all technical specifications of the original SAILOR Thrane & Thrane component. The high-flex design resists tangling, wear, and corrosion in salty or humid marine environments. Our technicians also offer on-site cord replacement and handset testing for maximum system uptime.
