Scanstrut DS30-P-3 Vertical Cable Seal *3-Pack

The Scanstrut DS30-P-3 Vertical Cable Seal 3-pack delivers professional-grade waterproof protection for antenna and navigation light installations on vessels of all sizes. Whether you're running rigging through the hardtop, mast, or cabin roof, these vertical cable seals eliminate the headaches of traditional sealants and silicone—which inevitably fail after years of UV exposure and thermal cycling. Designed by Scanstrut, a trusted name in marine electronics integration, this three-pack gives you multiple installations' worth of peace of mind, whether you're upgrading a single boat or outfitting a small fleet.

Each seal is engineered to IP68 waterproof certification, meaning it blocks water ingress even under submersion—critical when saltwater spray, rain, and washdowns are routine. The DS30-P-3 features a vertical orientation design that routes cables cleanly through deck penetrations without kinking or binding, reducing installation time significantly. The mechanism uses a compression-fit gland that adapts to various cable diameters, creating a permanent watertight barrier without requiring messy caulking, bedding compound, or re-sealing every few seasons. This design approach prevents the corrosion and electrical interference that loose, deteriorating seals invite into your electronics.

Installation is straightforward: route your antenna or nav-light cable through the seal before mounting, then secure the assembly into your deck or mast opening. Boaters who maintain their own electronics, professional riggers, and marine installers all recognize that a proven, guaranteed waterproof seal pays for itself the first time it prevents a short circuit or corrosion event. The three-pack format is ideal for boats with multiple antenna systems, VHF, GPS, and lighting runs—or for keeping backups on hand for future upgrades.
