Fine-adjustment control allows you to dial in the distance from the material edge in increments of 1/10mm for ultra-precise routing. Dust extraction hood enables ultra-efficient dust extraction, saving valuable cleanup time. The Edge Guide is constructed from durable cast aluminum, and includes fiber-reinforced plastic thumbscrews for easy adjustment and a long service life.
