Hoffmann Inside Corner Fences with Height Extensions are a helpful accessory when processing tall, thin material standing "on edge".
Shipped in a set of two, one for the left and one for the right hand side.
Also needed if the inside edge of the moulding is the reference edge. Generally, the outside edges are used with the center fence plate to locate the material on the machines. However, if the moulding varies in width, using the inside edge assures perfectly aligned inside corners. Any variations will be visible as off-set outside corner and can be sanded flush.
Inside Corner Fences are mounted on the fence rail to either side of the router bit, and secured with a locking lever.
Made of solid aluminum, with a special ridge on the underside to engage the fence rail.
