When attached to the Veritas Compact Router Base Plate, this fence and center kit lets you use the edge of a workpiece as a reference when making freehand cuts with a compact router. It can also be set to accurately guide the router when cutting arcs or circles. The 6" rods allow offsets from zero to 5" with the straight fences and diameters from 6 1/2" to 20 1/2" with the circle head.
