With an overall height of 8", this fence is perfect for raising panels vertically, shaping base molding and grooving the edges of wide boards. It also works great for everything a smaller fence can do. Full-length top fence provides continuous support across the gap, while the bottom fences are easily adjusted for different bit sizes. Included Bit Safety Guard (67157) keeps your fingers away from the bit. Heavy-duty aluminum fence provides excellent stability and a perfectly square reference surface. As you’ve come to expect from Rockler fences, all adjustments are simple and tool-free.
