Sea-Dog Line

<h3>About Sea-Dog Line</h3><p>Few names in the marine hardware world carry the same weight as <strong>Sea-Dog Line</strong>. Rooted in the early 1920s and headquartered in Everett, Washington, the company traces its origins to a uniquely inventive sales strategy: its founder, Hans &ldquo;Action&rdquo; Broson Sneve, showcased marine hardware by sailing his wares up and down the Pacific Coast aboard the M.V. Sea-Dog &mdash; a 55-foot cruiser that became the brand&rsquo;s namesake. That spirit of hands-on, on-the-water ingenuity has defined Sea-Dog ever since.</p><p>Today, Sea-Dog Line operates as the Sea-Dog Corporation, a third-generation family business that has expanded from a regional Pacific Coast distributor into a nationally recognized supplier of marine, industrial, and rigging hardware. The company serves everyone from professional shipbuilders to weekend boaters, earning repeat recognition from the National Marine Distributors Association for its supply chain standards and product quality.</p><h3>What Sea-Dog Line Makes</h3><p>Sea-Dog&rsquo;s catalog is remarkably broad. At its core, the brand specializes in providing hardware that must hold up in some of the harshest environments on earth &mdash; saltwater, UV radiation, temperature swings, and constant vibration. To meet those demands, Sea-Dog builds its products from marine-grade materials including 304 and 316 stainless steel, investment-cast bronze, chrome-plated brass, and UV-resistant injection-molded polymers.</p><p>The product lineup spans anchoring and docking hardware, deck fittings, cabin and hatch hardware, chain and rigging components, electrical panels, lighting, plumbing fittings, ventilation equipment, boat hooks, rod holders, and much more. Whether you&rsquo;re outfitting a new build or replacing a worn component, Sea-Dog likely has the part you need.</p><p>Among Sea-Dog&rsquo;s most well-regarded marine electrical and windshield products is their comprehensive lineup of <a href="/7549-sea-dog-line-windshield-wiper-motor-8824">Windshield Wiper Motors</a>. Engineered specifically for the marine environment, these motors feature corrosion-resistant aluminum and stainless steel construction, adjustable sweep angles, and a &ldquo;coast-to-park&rdquo; function that automatically returns the blade to its set position when power is cut &mdash; exactly the kind of thoughtful design detail that sets Sea-Dog apart from generic alternatives.</p><h3>Why Boaters Trust Sea-Dog Line</h3><p>Sea-Dog&rsquo;s longevity in the marine hardware market is no accident. The brand has built its reputation on producing components that align with ABYC (American Boat and Yacht Council) standards, giving boat builders and DIY installers confidence that each part meets recognized safety benchmarks. Products are designed for both recreational and commercial applications, meaning whether you&rsquo;re a weekend angler or a working captain, Sea-Dog hardware is built for your level of use.</p><p>With over a century in the marine industry, an ever-expanding product catalog, and a family-run culture that keeps quality at the forefront, Sea-Dog Line remains one of the most trusted names on the water. Browse the full Sea-Dog lineup to find the right hardware for your vessel.</p>

Product Details

The Sea-Dog Line Dripper Guard Large White 3-Pack (MPN: 520848-1) is a patented thru-hull stain guard designed to keep your boat's hull looking clean and streak-free. Water draining through thru-hulls can leave unsightly black streaks and mineral deposits on your hull — the Dripper Guard eliminates that problem at the source.

Made from Nitrile-Buna (NBR) rubber, each guard installs directly beneath your thru-hull fitting using a 3M pressure-sensitive adhesive backing. The patented channel design captures and redirects dripping water outward and away from the hull surface, preventing staining and water sediment buildup. This value 3-pack is ideal for boats with multiple thru-hull fittings.

Key Features:

  • Prevents ugly black streaks and staining on the hull exterior
  • Patented channel design redirects water away from the hull surface
  • Made from durable, UV-resistant Nitrile-Buna (NBR) rubber
  • 3M pressure-sensitive adhesive backing for secure, easy installation
  • DIY install — prep surface, peel backing, and press into place along the bottom edge of thru-hull
  • Large size fits thru-hull outside diameters from 1-7/8" to 2-5/8"
  • White finish to complement light-colored hulls
  • Value 3-pack — perfect for multi-thru-hull applications
  • For use above the waterline only

The Sea-Dog Dripper Guard is a simple, cost-effective way to protect your boat's appearance and reduce hull cleaning time. Three guards are included, making this pack a great choice for cruisers, sailboats, and powerboats with multiple through-hull fittings.
