Material: Plastic; Color: Black. Inside dimensions: 1″ W x 1/2″ H. Sold as a pair. Best for smaller rub rails and budget builds where corrosion isn’t a concern.

T-H Marine Rub Rail End Cap, Black
Finish: Black rub rail end cap with insert. Fits 1-1/2″ wide rubber molding and secures with screws to prevent slip-out. Best for a robust, secure finish on mid-size rub rails. Choose this if you value a stable, screw-secured installation; caution: requires drilling for installation.

Buying Guide
What to consider when selecting boat rub rail end caps
- Fit and compatibility: Check the rail width and molding type (rub rail vs. rubber molding) to ensure the cap seats properly. Some caps are model-specific, especially for Taco Marine profiles.
- Material and environment: Plastic is budget-friendly and light; nylon offers good impact resistance; stainless steel provides the best corrosion resistance in saltwater; consider climate and exposure.
- Installation method: Caps that screw through trim offer secure retention but require tools; snap-on or insert-equipped caps can be easier to install on some rails.
- Aesthetics: Match color and finish to your rub rail for a seamless look. White or black can work with most hull colors.
- Durability vs. cost: Stainless steel lasts longer in harsh conditions but costs more; plastic and nylon are lighter and cheaper but may wear faster.
- Maintenance: Consider how easy the cap is to clean and how it holds up under UV exposure and salt spray.
