Starboard SUP US Box 14″ Fin Box – Rounded Edge for Hard SUP

Starboard SUP US Box 14″ Fin Box – Rounded Edge Version for Hard SUP Boards

Upgrade or repair your paddleboard with the Starboard SUP US Box 14″ (≈ 35.5 cm) Fin Box, designed specifically for solid (hard) SUP boards. This version features rounded edges for a smoother fit and finish, and a rear-entry system, meaning your fin slides in from the back instead of the center.

Why choose this fin box?

• Perfect replacement if your old box is cracked, loose, or damaged.

• Ideal for board builders looking to use the exact same system found in original Starboard boards.

• Rear-entry installation makes mounting and adjusting your fin simple and secure.

As with all Starboard components, this fin box is built with the highest quality standards. Starboard is recognized worldwide as the #1 SUP brand, trusted for durability, precision, and innovation.

Compatible with the US Box fin system, it allows you to experiment with different fins and riding styles. At 14″ in length, it ensures stability, strength, and reliability session after session.

With Starboard parts, you’re not just replacing — you’re upgrading.
