This micro-adjustable stop rides in the Router Boss guide rail t-tracks. It provides exact adjustment in fitting tenons, sliding dovetails, and other joints. A quarter-turn of the adjustment head equals 1/4mm or 1/100". Includes a 10mm stop rod that fits into the router edge guide hole of most routers.
The two plastic stops that come with each Router Boss machine can also be used in the guide rail t-tracks, but are not micro-adjustable.
