Template guides are a great guide for a router giving a very controlled cut using a pattern or template. The guide attaches to the router base to keep the bit a specific distance from the template's edge while allowing the bit to cut into the workpiece. Precision machined for added accuracy. Make sure to choose a template guide that has an inner diameter larger than the bit you intend to use. This template guide fits Porter-Cable routers and many other standard routers. Requires 42237 lock nut for installation (sold separately).
