Seal the Ends. Protect the Boat. Protect Yourself.

The open ends of your inflatable boat’s aluminum side rails are an accident waiting to happen — sharp metal edges that scratch your hull, cut your hands, and let seawater in to corrode from the inside out. The RIVOWON Aluminum Rail Rubber End Cap snaps on by hand in seconds, sealing the profile end with a tight rubber cover that eliminates every one of those risks.

🔒 Waterproof Seal – Stops Corrosion at the Source

Precisely molded rubber cap blocks the open end of aluminum profiles, preventing rain and seawater from penetrating inside and causing oxidation, rust, and internal corrosion.
Keeps your aluminum rails looking clean and performing structurally sound, season after season.

🛡️ Safety First – Covers Sharp Metal Cross-Sections

Eliminates exposed sharp aluminum edges that can scratch your boat hull, cut hands, snag clothing, and damage gear stored nearby.
Smoother, safer boat — especially important in tight spaces and when passengers are boarding or moving around.

📌 Tight Clip-On Fit – Stays Put in Rough Conditions

Integrally injection-molded with a clip-on retention structure that grips the aluminum profile firmly — won’t vibrate loose, pop off, or shift during bumpy sailing or rough water.
Precisely sized to match the profile cross-section for a snug, wobble-free fit.

☀️ UV & Weather Resistant – Built for Marine Environments

Made from high-density seawater-resistant rubber that is anti-aging, UV-stable, and resistant to extreme temperatures.
No hardening, no cracking, no fading — maintains flexibility and grip through years of sun and saltwater exposure.

⚡ Press-Fit Installation – No Tools, No Adhesive

Simply press on by hand — the cap clicks into place in seconds with no glue, screws, or tools required.
Easy to remove and refit when needed for rail maintenance or profile replacement.

Seal it right. Sail with confidence. That’s RIVOWON.
