The Slide & Lock system was designed by JA Master Bench Jeweler Jeff Mathews to help jewelers work more efficiently. By simply opening the brass handle you can quickly reposition the height of your work for easy adjustments or to move to the next task. This will save time moving through the steps of fabrication and setting. The system is ideal for anything that attaches to the GRS Fixed Mounting Plate (#004-557). This includes any of the BenchMate® models, Block Shelf, Bench Pin, Multi-Purpose Vise, and more. The Slide & Lock Mini accommodates 5" of travel.
