The GRS Universal Positioning Pin Vise Attachment works with all ball vises. It works much like the GRS Center Positioning Ball Vise (see related products below), in that it allows you to re-position your work quickly and easily without the need to re-position your microscope or the engraving ball itself. Once you have your work secured in the attachment, simply loosen the jaws of your ball vise and slide or rotate the attachment so that the area you're working on is centered in your scope. With practice, you won't even have to take your eyes away from your microscope.

Machined from solid stainless steel with a self-centering jaw system. The rotational resistance can be adjusted from free-rotating to locked. Includes four 3/32" steel pins, four 3/32" brass pins, MicroBlock rubber base, and 5 mm hex wrench. Made in USA.
