Description:

The Unifiber 12mm Fin Insert UF600000064 is a precision replacement part designed to restore or upgrade the fin mounting interface in Powerbox-equipped boards. Engineered for secure blade attachment, the insert provides a tight, low-profile fit that transfers thrust efficiently from the fin to the board.

Easy to install and built for durability, this fin insert is ideal for sailors, surfers and paddlers who demand reliable performance from their fin system. Compatible with standard Powerbox fins and hardware, it’s an essential spare for repairs, maintenance, and rigging upgrades.
