The EB-3 Osborne miter guide from Excalibur by General International features a patented triangular design that offers rock solid support of the work piece at any angle setting and anywhere on its face. Equipped with a sliding stop that flips up out of the way when not in use, and a telescopic fence extension that can offer work piece support up to 42-inches from the blade, the EB-3 Osborne miter guide is a very practical addition to any table saw. The patented extension arm assembly makes it possible to quickly and easily find any angle and lock it securely in place, and the precision detent plunger auto-locates common angles quickly. The fence can be adjusted from side to side allowing tight clearance to the blade for clean precision crosscuts and the entire assembly is reversible in seconds for use in either miter slot. A removable heavy-duty steel T-slot washer holds the guide bar snug to the table, the 3 guide bar expansions screws allow for a custom fit to your saw to remove any play in the miter slot, and a simple to use lockable calibration mechanism allows you to make precision angle adjustments when needed.
