The Lock Miter Master Jigs require virtually no test cuts. With these jigs you can quickly and easily set the proper bit height and fence position for precise-fitting lock miter joints. The jigs attach securely to the lock miter router bit with rare-earth magnets. They are precision-milled with laser-engraved reference lines that make it easy to set the bit and fence for perfect cuts.
