Sea-Dog Line

<p>For over a century, Sea-Dog Line has stood as a cornerstone of the marine hardware industry, delivering innovative solutions that meet the demanding needs of recreational and commercial boaters. Founded in the early 1920s by entrepreneur Hans "Action" Broson Sneve, the company began with a unique sales approach—showcasing marine hardware aboard a 55-foot cruiser that sailed from Alaska to Mexico. This hands-on philosophy continues to shape Sea-Dog's commitment to producing hardware that performs reliably in the harshest saltwater environments.</p><h3>Industry-Leading Marine Hardware Manufacturing</h3><p>Based in Everett, Washington, Sea-Dog Corporation operates a 75,000-square-foot warehouse stocking over 8 million parts and runs an injection molding facility with 16 machines producing more than 17 million components annually. The company's extensive product line spans anchoring systems, deck hardware, electrical components, plumbing fittings, and lighting solutions—all engineered with marine-grade materials like stainless steel, brass, and UV-resistant polymers. Sea-Dog's recognition as a multiple-time NMDA Supplier of the Year underscores the brand's excellence in both product quality and customer service, while their on-staff ABYC-certified marine technician provides invaluable installation and technical support.</p><h3>Premium Marine Components for Every Vessel</h3><p>Sea-Dog's <a href="/7549-sea-dog-line-windshield-washers-wipers-replacement-motors-201195">windshield washers, wipers, and replacement motors</a> deliver crystal-clear visibility during inclement weather, with both manual and electric options featuring corrosion-resistant stainless steel arms and UV-stable blades designed specifically for marine windshield applications.

Product Details

The Sea-Dog Dripper Guard® 3M® Adhesive Stain Guard is a simple, effective solution for keeping your boat's hull free from the unsightly black streaks and water sediment stains that drip down from thru-hull fittings. Featuring a patented channel design, this guard redirects water out and away from the hull rather than letting it run down the side.

Key Features:

  • Stops hull staining — prevents black streaks and water sediment buildup on the side of your boat
  • Patented channel design redirects drips away from the hull for clean, stain-free results
  • 3M high-strength adhesive system provides a secure bond between fiberglass and polymer rubber
  • Soft polymer rubber construction allows the guard to flex and bend, surviving pressure washing and dock contact
  • UV-protected material resists fading and cracking for long-lasting performance
  • Easy DIY installation — simply prep the surface, peel the 3M backing, and press into place along the bottom edge of your thru-hull
  • Fits thru-hulls up to 2-5/8" outside diameter

The Dripper Guard is an ideal maintenance accessory for any boater looking to preserve their hull's appearance with a quick, no-tool installation. Backed by a one-year limited warranty.
