Sea-Dog Line 520848-1 Dripper Guard Large White 3-Pack Thru-Hull Stain Guard

The Sea-Dog Line Dripper Guard Large White 3-Pack (MPN: 520848-1) is a patented thru-hull stain guard designed to keep your boat's hull looking clean and streak-free. Water draining through thru-hulls can leave unsightly black streaks and mineral deposits on your hull — the Dripper Guard eliminates that problem at the source.

Made from Nitrile-Buna (NBR) rubber, each guard installs directly beneath your thru-hull fitting using a 3M pressure-sensitive adhesive backing. The patented channel design captures and redirects dripping water outward and away from the hull surface, preventing staining and water sediment buildup. This value 3-pack is ideal for boats with multiple thru-hull fittings.

Key Features:

• Prevents ugly black streaks and staining on the hull exterior
• Patented channel design redirects water away from the hull surface
• Made from durable, UV-resistant Nitrile-Buna (NBR) rubber
• 3M pressure-sensitive adhesive backing for secure, easy installation

• Large size fits thru-hull outside diameters from 1-7/8" to 2-5/8"
• White finish to complement light-colored hulls
• Value 3-pack — perfect for multi-thru-hull applications
• For use above the waterline only

The Sea-Dog Dripper Guard is a simple, cost-effective way to protect your boat's appearance and reduce hull cleaning time. Three guards are included, making this pack a great choice for cruisers, sailboats, and powerboats with multiple through-hull fittings.
