The rail on the bottom of this GRS® universal positioning vise quickly turns any GRS vise into a positioning vise that is ideal for working under a microscope. The smooth, self-centering jaw system (1-5/16" max. opening) is perfect for precision work such as fine detailed engraving and stone-setting. The jaws feature a number of holes, making it easy to configure your holding accessories for precise positioning as you work. The jaws are machined from solid stainless steel and finished with a special low-glare treatment to reduce eye strain. This positioning vise includes a MicroBlock® rubber base, eight pins (four steel, four brass) and an Allen wrench.
