Product Details

The Sea-Dog Line 520841-1 Thru-Hull Drip Redirector is a simple, effective solution for eliminating unsightly black streaks on the side of your boat caused by water dripping from thru-hull fittings. Designed for easy owner installation, this self-adhesive redirector requires no special tools or skills to mount.

Key Features:

  • Prevents Black Streaking: Stops dirty water from running down the hull and leaving dark stains on your boat's finish
  • Patented Channel Design: Engineered channel redirects water outward and away from the hull surface, eliminating drip-down entirely
  • Easy DIY Installation: Simple peel-and-press application — prep the surface, peel the backing, and press firmly along the bottom edge of your thru-hull fitting
  • Self-Adhesive Backing: Secure, marine-grade adhesive backing ensures a long-lasting bond in wet, saltwater, and freshwater environments
  • Discreet Low-Profile Fit: Mounts neatly along the base of the thru-hull with a clean, finished appearance

Keep your hull looking its best with the Sea-Dog 520841-1 Drip Redirector — an affordable, maintenance-saving addition to any powerboat or sailboat with below-waterline or above-waterline thru-hull fittings.
