The Seneca Woodworking Imperial Thickness Gauge for the DOMINO DF500 allows you to quickly and effortlessly adjust the DOMINO fence offset to center your mortise on a variety of imperial material thicknesses. The gauge installs in less than a minute using a Torx T10 bit (not included), and is a direct replacement for the metric thickness gauge included with your DOMINO DF500.

The Imperial Thickness Gauge is designed to center on 1/2", 5/8", 3/4", 7/8", 1", and 1-1/8" nominal plywood thicknesses (undersized from dimensional lumber).
