This is a simple yet accurate tool for your boy or girl scout to measure their pinewood derby cars. It is sized for U.S. Pinewood Derby regulation. This has slots that require 1/16" plexiglass or acrylic sheets to be glued in for the sides. Measurements are imprinted on the sides and top, so the judges can verify your measurements, and it has 2 recessed boltholes in case you want to bolt or screw it down to a table.
