About Empire

In its first three years, Empire created the adjustable level with interchangeable and replaceable vials. They followed this first success with a series of innovations: the torpedo level, the Mono vial, the magnetic level and the first extruded aluminum rafter square. The company also introduced top read levels, Monster vials, interlocking T-Squares and invented the snap-in vial. They currently hold more than thirty active patents.
