The Pro Stop by Edge Technology is the world's first vise stop with the CNC machinist in mind. Its super low profile design stays completely below the top surface of the vise which means it will not interfere with cutting tool paths. Whether you are making 10 parts or 10,000 parts the ultra rigid Pro Stop will not move once you lock it down. It is an ideal datum surface to locate parts. The Pro Stop is extremely versatile allowing the hardened steel stop rod to be quickly positioned in any location needed.
