Inspired by master engraver Sam Alfano, the GRS Design and Layout Surface is a convenient multi-purpose work surface that mounts into a GRS vise. The 6-inch diameter provides a large work area. Covered with quality genuine leather for a soft surface that will not damage fine workpieces. Using the Design and Layout Surface provides a flat, stable area for layout under the microscope. Other uses include inspection, assembly, working surface for oddly shaped items, drawing table, and more. Fits in all GRS vises.
