Sea-Dog Line 520842-1 Thru-Hull Drip Stop Streak Preventer

The Sea-Dog Line 520842-1 helps stop black streaks from staining the side of your boat. It mounts along the bottom edge of a thru-hull fitting and keeps water from running down the hull, so the hull stays cleaner.

Key Features:

• Helps prevent black streaks and stains on the side of the boat
• Patented channel design redirects water out and away from the hull, preventing drips down the hull side
• Easy do-it-yourself installation: peel the backing and press along the bottom edge of the thru-hull

A simple way to reduce hull streaking and cut down on cleaning around thru-hull fittings.
