Scanstrut Cable Clamps

Scanstrut Cable Clamps: Engineered for the Marine Environment

When it comes to managing cables aboard a boat, the stakes are high. Salt spray, constant vibration, UV exposure, and moisture can turn a poorly routed cable into a costly repair — or worse, a safety hazard. Scanstrut, a British brand with cable clamp and cable seal solutions at the core of its identity, was built precisely for these challenges. For over 40 years, the company has been designing and manufacturing equipment engineered to withstand the toughest marine environments.

Scanstrut's reputation as a leader in cable management isn't accidental. The brand describes itself as the #1 choice worldwide for cable seal technology, and its cable clamp and seal lineup reflects the depth of engineering behind that claim. Every product is designed in-house — from concept to production — and put through up to 30 rigorous tests before it ever reaches the market. That process shows in the precision fit, material quality, and long-term reliability that boat owners and professional installers have come to expect.

What Sets Scanstrut Cable Clamps Apart

Scanstrut's cable management products are not generic hardware-store clamps repurposed for marine use. Their range is purpose-built for the specific demands of onboard cable routing. Key features across the lineup include:

• IPX6 and IPX7 tested and approved — delivering true waterproof performance, not just splash resistance.
• Marine-grade materials — options include UV-stable high-impact plastic, glass-filled nylon, and marine-grade aluminium with a hard finish to resist impact marks.
• Split pre-drilled bungs on select models, which allow cables with connectors already attached to pass through without cutting and re-terminating — a major time-saver during installation.
• Captive nuts built into the base for easy assembly and reliable repeat installations.
• Closed-cell base seals supplied on all units, ensuring a 100% watertight fit at the mounting surface.
• Low-profile construction on horizontal entry models, which keeps the cable exit as close as possible to the mounting surface for a clean, professional look.

The range covers a wide variety of installation scenarios. Vertical entry seals like the compact DS6-P handle cables from 2–6mm with a dome-shaped, impact-resistant profile. Horizontal entry models such as the popular DS-H10 accommodate cables from 6–10mm. For runs involving multiple cables, the DS-H-MULTI series handles multiple cables up to 15mm in diameter with a compact footprint and clean installation. There are even Starlink-compatible cable seals — the DS-HSL-01 — purpose-designed for satellite antenna installations on boats, RVs, and other platforms.

Why Boaters Trust Scanstrut for Cable Management

Sloppy cable routing with silicone sealant may hold temporarily, but it fails over time in a marine environment. Scanstrut's range eliminates that approach entirely — their solutions are the only guaranteed and proven watertight installation method for antenna, nav light, and electronics cables. The result is a cleaner helm, a drier bilge, and peace of mind on every passage.

Whether you're running a single transducer wire through a fiberglass deck or routing solar, electronics, and lighting cables through a bulkhead on a bluewater cruiser, Scanstrut's cable clamp lineup has a purpose-built solution.
