4.5" Classic Center Fin – Smoke Pro Glass.

Compact, clean, and predictable — a classic small center fin for added control without killing speed.

The 4.5" Classic Center Fin is a compact single-fin designed to add stability, control, and smooth release to shorter boards, mid-lengths, and performance-oriented setups. Its traditional outline delivers reliable hold through turns while maintaining a fast, lively feel.

Made from durable smoke Pro Glass, this fin offers a balanced flex pattern that smooths out transitions and enhances board feel without feeling stiff or tracky. The smaller 4.5" height allows for easy direction changes, making it ideal for surfers who want subtle control rather than heavy drive.

This fin works exceptionally well in single-fin shortboards, mid-lengths, and 2+1 setups where a refined center fin improves confidence without overpowering the board.
