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.
