Scanstrut TBH-10 Through Bulkhead Cable Seal

The Scanstrut TBH-10 Through Bulkhead Cable Seal is a marine-grade solution designed to prevent water intrusion where cables pass through boat hulls and bulkheads. After years running electronics on the water, any experienced angler or boater knows that a single leak at a cable penetration can spell disaster for navigation systems, fish finders, and electrical connections. This seal addresses that vulnerability head-on, protecting your investment in marine electronics and ensuring watertight integrity where it matters most.

Built by Scanstrut, a trusted name in marine cable management, the TBH-10 uses a compression-fit design that accommodates various cable diameters while maintaining a reliable weather seal. The bulkhead fitting creates a positive grip around your cables without requiring extensive modification to existing installations, and its compact footprint (4 x 4 x 5 inches) fits neatly into tight spaces typical of modern boat layouts. The robust construction resists salt-spray corrosion and UV degradation—critical performance factors for anything exposed to the harsh marine environment.

This seal is ideal for protecting power cables, network lines, and sensor wiring that run through hull penetrations on recreational boats, center consoles, and fishing vessels. Whether you're upgrading your electronics suite, reinstalling equipment after service, or addressing a problematic leak, the TBH-10 installs quickly and requires no special tools. Compatible with standard cable bundles, it delivers the watertight barrier that keeps saltwater out and keeps your electronics running reliably for season after season on the water.
