Original Slide & Lock (#004-757)
Tru-Axis Adapter (#004-753)

The Slide & Lock system was designed by JA Master Bench Jeweller Jeff Mathews to help jewellers work more efficiently. The Tru-Axis Adapter was designed for those that own the Original Slide & Lock (#004-757) and work under a microscope. Once installed the user is able to maintain a set height of the Slide and Lock, allowing the Tru-Axis Adapter to travel up to 4" vertically without contacting the microscope. 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 adapter must be paired with the Original Slide & Lock. The system interfaces with any tool that attaches to the GRS Fixed Mounting Plate. This includes any BenchMate® models, Block Shelf, Bench Pin, Multi-Purpose Vise, and more.
