Surfboard Fin Angle Tool - Adjustable Protractor

Precision fin cant is critical for the performance of any surfboard. Our Surfboard Fin Angle Tool is a professional-grade protractor designed to help you quickly determine and set the exact angle of your fin boxes or glass-on fins. By providing a clear, stable reference point against the bottom of the board, this tool takes the guesswork out of your layout and ensures your fin setup is perfectly symmetrical.

The tool is highly intuitive and accurate to within 1 degree, allowing for the micro-adjustments required for high-performance thrusters, quads, and twin-fin setups. It features an easily adjustable pivot arm with a secure locking nut to hold your desired angle while you work. Made from durable, high-visibility material, it is easy to locate in a dusty shaping bay and built to withstand the rigors of professional surfboard production.

Key Features:

• Precision Accuracy: Easily adjustable and accurate to 1 degree for professional fin cant settings.
• Quick Setup: Designed for rapid angle checking during the fin-setting process.
• Locking Adjustment: Features a knurled thumbscrew to lock in your specific angle for repeatable results across both sides of the board.
• High Visibility: Bright yellow construction makes it easy to find on a busy, foam-covered workbench.
• Versatile Use: Essential for setting cant on FCS, Futures, and traditional glass-on fin systems.

Pro Tip: To ensure perfect symmetry, set the angle on one side of the stringer, lock the tool, and then flip it to the other side. This ensures both your left and right fins have the exact same degree of cant for a balanced ride.
