Most sliding T-bevels perform a single function – setting bevels. BORA’s performs four. In addition to functioning as a standard T-bevel it has a vial for leveling, a 1/16th inch scale on the blade for measuring, and notch along one edge that allows it to be used as a guide for marking 3/16-inch trim reveals.
