Selection rationale: versatile fit and secure attachment via screw-through design. Caution: ensure pilot hole locations align with your trim pieces to avoid misalignment.

Buying Guide
What rub rail material is best for your boat? Consider aluminum, stainless steel, nylon, or plastic caps based on corrosion resistance, weight, and durability. How do you measure fit? Check overall rail width, height, and corner geometry; many caps specify compatible dimensions. Are you prioritizing aesthetics or rugged protection? Stainless steel and polished finishes suit classic boats, while black nylon and matte plastics work well for budget builds. Is installation easy? Some caps screw through trim for a secure hold; others snap or glue in place. Consider your maintenance routine and exposure to saltwater when choosing.
