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 Line 321489-1 is a gas-filled lift spring designed to provide smooth, controlled assistance for hatches, lids, engine covers, and access panels on boats and marine applications. This nitrogen gas-charged strut delivers 90 pounds of lifting force with a 20-inch extended length, making it ideal for medium to heavy-duty marine hardware applications.

Key Features:

  • 90 lb lifting force provides reliable support for hatches and compartment lids
  • 20-inch extended length for versatile installation options
  • Nitrogen gas-filled design ensures consistent, smooth operation
  • Marine-grade construction resists corrosion in harsh saltwater environments
  • Sealed design prevents gas leakage and maintains pressure over time
  • Easy bolt-on installation with standard mounting hardware

Gas lift springs are essential components for safe and convenient access to storage compartments, engine bays, and other enclosed areas on boats. The controlled damping action prevents hatches from slamming shut while providing enough force to hold them open securely. Sea-Dog Line's marine-grade construction ensures long-lasting performance even in demanding saltwater conditions.
