The Surfboard Studio Layout Square
The Surfboard Studio Layout square is an essential tool for measuring fin positioning and placement. This easy to use product gives you accurate measurements from stringer to rail and allows you to quickly measure mid-point, nose and tail. Made from a flexible, clear polycarbonate sheet, which sits perfectly flat on the surfboard blank (with enough bend to follow your rocker line). 
Layout square dimensions - 625mm x 340mm
