The UJK Guide Bush adaptors allows UJK guide bushes (US threaded type) to fit to the base of different model routers, meaning you can add optional bush sizes for various template routing requirements. When using the UJK dovetail jig, having a router fitted with a guide bushing is essential, however you may need an adaptor to fit your guide bush as routers are not standardised. UJK offers a range of adaptors to bridge this gap. N.B. See Technical Data Sheet in Information Downloads for router combability chart.-bg
