The 4.5" Classic Center Fin – Old Red Pro Glass is designed to free up your board while retaining smooth, predictable control. Its smaller height and classic outline reduce drag and encourage quicker rail-to-rail transitions, making it ideal for surfers who want a more responsive feel from their setup.

Hand-finished in old red Pro Glass, this fin delivers a balanced, organic flex that feels forgiving yet connected — softer and more flowing than carbon or G10. Perfect for mid-lengths, eggs, and longboards run as a 2+1, where looseness and flow matter.

Why Choose a 4.5" Center Fin?

A smaller center fin dramatically changes board feel. At 4.5 inches, this fin reduces resistance and frees up the tail, making turns faster and more fluid. It’s a great option if a larger center fin feels stiff or tracky, or if you want to inject life into a 2+1 setup.

FAQs

What fin box does this center fin fit?
This fin fits a standard sliding center fin box (single fin box) and installs using a fin screw and plate.

Is a 4.5" center fin suitable for a single-fin longboard?
Generally no. This size works best in a 2+1 setup or on mid-lengths where looseness and responsiveness are the goal.

How does Pro Glass feel compared to carbon or G10 fins?
Pro Glass offers a smoother, more forgiving flex, delivering a classic surf feel with better flow than stiffer materials.
