Similar in design to the WACO Seam Thickness Gauge, this gauge is designed to measure the flange width of open ended cans. The spring loaded can guides automatically position the can for fast, accurate, and repeatable measurements. Constructed of machined stainless steel for corrosion resistance and long life. The base plate is reversible to double the wear life of the surface. The WACO Flange Width Gauge is suited for round cans with diameters from 2" to 6.5".
