What is unclear is that there are several types of work stops. See links below:

The five-axis work stop is a new machine tool accessory. The work stop has been designed to meet and defeat problems associated with almost every type of milling work stop used in today's machine shop. The five-axis work stop is said to eliminate the need for numerous work stops previously required.
The work stop is compact and single mounts via t-nut to any size table base or machine. It requires minimum table area, allowing machinists maximum table room for additional work stops or vises. Work stop interference with the machine tooling is said to be eliminated as well.
The work stop locks in quickly and easily by securing two allen blots with a tong arm alien wrench. It has an adjustable sliding stop bar that is 8" long with a ball end and is easily maneuvered into many different positions.
