With over 13,000 square feet of manufacturing and warehouse facilities, the factory houses some of the most high-tech CNC equipment including 4 Monarch, 2 Haas machining centers and 3 CNC lathes. Milling machines, gear cutting machines and a vast array of manufacturing equipment are busy nearly 24-hours a day maintaining the product line.
