Designed to enable virtually any router to cut ellipses and circles. Used for corner tables, arches, desks and mirrors. Setting-up and operating is simple and effective, as proven by existing industrial users. A connector plate on the end of the bar fits directly onto the fence rods of Trend routers. For the fixing of other makes of routers, an accessory adaptor base plate is required. By using one slide, the jig can be adapted for cutting circles. With additional extension bars, larger ellipses and circles can be cut.
