Surfboard Rail Contour Gauge - Symmetry & Profiling Tool

Achieve absolute symmetry on every build with the Surfboard Rail Contour Gauge. While the "feel test" is a staple of shaping, this precision tool provides a visual and physical reference to ensure your rails are identical from side to side. It is the ideal solution for shapers looking to eliminate guesswork and deliver a professional, balanced shape.

The gauge features a series of high-density pins that conform to any curve when pressed against the rail. Simply "lock" the shape of your perfected rail on one side of the stringer, then carry it over to the corresponding point on the opposite rail to check for high spots or deviations. Beyond symmetry, this tool is invaluable for builders looking to "scan" and replicate the rail transitions of a favorite board for a custom recreation.

Key Features:

• Precision Symmetry: Instantly compare rail profiles from the left and right side of the board.
• Instant Profiling: Perfectly captures complex rail curves, tucked edges, and apex points.
• Non-Marring Pins: Designed to be pressed against foam or fiberglass without leaving marks or dings.
• Replication Tool: Excellent for tracing and documenting specific rail shapes for future shapes.
• Durable Construction: Built to withstand the dusty environment of the shaping bay.

Pro Tip: Use the gauge at three key points—the wide point, 12" from the nose, and 12" from the tail. This ensures your rail foil is consistent and flowing correctly through the entire length of the board.
