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 337165-1 is a 6-inch screw-out deck plate designed for secure access to storage compartments on boats and marine vessels. Constructed from high-quality UV-stabilized plastic with advanced antioxidants, this deck plate resists sun damage and weathering for long-lasting performance in harsh marine environments.

Key Features:

  • 6-inch diameter screw-out design for easy access to storage areas
  • UV-stabilized construction prevents fading and cracking from sun exposure
  • Antioxidant additives protect against saltwater corrosion and degradation
  • Black finish complements most boat deck colors
  • Threaded design creates watertight seal when properly installed
  • Durable molded construction for reliable performance

Installation and Maintenance:

For proper installation, apply silicone sealant to the hull or deck surface before mounting to ensure a watertight seal. Keep threads clean by washing regularly with hot soapy water to prevent salt buildup and ensure smooth operation. Lubricate threads periodically with petroleum jelly or Teflon-based lubricant to maintain easy opening and closing.

This deck plate provides convenient access to below-deck storage, battery compartments, or plumbing systems while keeping water out when secured. Ideal for sailboats, powerboats, and other marine applications requiring secure deck access points.
