Scanstrut DS21B-P-BLK Vertical Cable Seal - Black

The Scanstrut DS21B-P-BLK Vertical Cable Seal in Black is a marine-grade cable management solution engineered for watertight installations on antenna and navigation light systems. With an IP68 waterproof rating, this cable seal delivers proven protection against saltwater intrusion, corrosion, and environmental degradation—critical requirements for vessels operating in demanding offshore and coastal environments where cable failure creates operational downtime and safety risks.

The vertical cable seal design simplifies installation while maintaining a 100% waterproof barrier around antenna and navlight cables at deck penetration points. Each unit arrives with both pre-drilled and blank inner seals, allowing technicians to match existing hole patterns or customize for unique applications. This dual-seal configuration reduces installation time compared to traditional cable glands and eliminates the guesswork common with generic waterproofing methods. The compact profile—4 inches long with a 1-inch diameter—fits tight spaces aboard modern vessels without requiring structural modification or cable rerouting.

Marine technicians, vessel operators, and riggers responsible for antenna systems, VHF radio installations, and navigation lighting rely on Scanstrut cable seals to prevent the water intrusion that degrades electronics and creates warranty voids. The IP68 standard ensures protection under continuous immersion and spray conditions, making this seal equally effective on fishing vessels, offshore support craft, and performance yachts. Black anodized finish resists corrosion in salt air environments and blends seamlessly with mast and rigging installations.
