Ring Gauge Holders
Often used with go and no-go ring gauges, these holders keep two ring gauges still for quick, repeat measuring. Since they're a stable platform, you can measure your shafts, rods, and other cylindrical parts from a consistent angle every time. Loosen the socket head screw to separate the two-piece construction and slot your rings in. Made of black anodized aluminum, they stand up to the friction from switching out rings. They also resist corrosion.
