When used with the Festool OF 2200 Router, the Edge Guide allows you to rout up against, or perfectly parallel to the material edge, delivering precise dados, flutes, grooves, ploughs, rabbets and profiles. Fine-adjustment control allows you to dial in the distance from the edge in increments of 1/10mm for ultra-precise routing. The Edge Guide is constructed from durable cast aluminum, and includes fiber-reinforced plastic thumbscrews for easy adjustment and a long service life. Attaches quickly and easily using integrated thumbscrews and two steel guide rods ST-OF 2200/2.
