Shaper Supply Shaper Square Pro - Fin Placement & Width Tool

The Shaper Square Pro is the ultimate multi-tool for the precision surfboard builder. Designed by industry veteran Florian Saylor, this professional version expands on the standard shaping square by integrating a dedicated fin placement tool directly into the layout. This allows you to accurately mark your fin positions, toe-in, and cant in one seamless workflow without switching between multiple templates.

In addition to fin layout, the Shaper Square Pro features high-visibility scales specifically calibrated for calculating surfboard widths and ensuring perfect symmetry from nose to tail. Proudly made in the USA, this tool is constructed from durable, high-impact materials designed to withstand the daily environment of a busy shaping bay. Whether you are truing your outline or setting up a complex quad fin cluster, the Pro Square provides the professional-grade accuracy required for high-performance builds.

Key Features:

• Integrated Fin Placement: Built-in scales and guides for fast, accurate marking of fin boxes and plugs.
• Symmetry & Width Scales: Precision-calibrated for calculating half-widths and ensuring a perfectly balanced outline.
• Professional Layout: Designed by Florian Saylor to streamline the transition from foam blank to finished shape.
• Made in the USA: Built to the highest standards of durability and accuracy.
• High Visibility: Easy-to-read markings that won't fade or wear off in a dusty shaping environment.

Pro Tip: Use the built-in fin tool to ensure your trailing fins are perfectly symmetrical relative to the stringer. The integrated square allows you to check your tail width and fin marks simultaneously for a faster, more accurate setup.
