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 521600-1 is a tiller rope grommet and hole liner designed to protect wires, cables, and ropes passing through bulkheads and access holes on boats and marine vessels. The raised lip edge securely captures the panel edge for a clean, finished appearance while guarding against chafe and wear.

Key Features:

  • Injection-molded polyethylene construction for durability and resistance to moisture, UV, and corrosion
  • Protective small lip keeps the liner seated in access holes and prevents edge chafe
  • Ideal for wire and cable pass-throughs, tiller rope routing, fishing rod storage through bulkheads, and general access holes
  • Installs with two flathead (FH) fasteners — fasteners not included
  • Available in black (521600-1) and white (521601-1)

Dimensions:

  • Cutout / Inside Diameter (C): 3"
  • Overall Outside Diameter (A): 4-1/16"
  • Inner Lip Diameter (D): 2-9/16"
  • Thickness (B): 3/8"
  • Flange Height (E): 3-1/2"

The Sea-Dog 521600-1 hole liner grommet is a simple, effective solution for any marine application requiring a neat, protected cable or rope penetration through a panel or bulkhead.
