The GRS® Design and Layout Surface is a convenient multi-purpose work surface that mounts into all GRS vices. The six-inch diameter provides a sufficiently large and stable work surface, allowing users to safely carry out any work that could benefit from microscope magnification. It is covered with high-quality genuine leather for a soft surface that will not damage fine workpieces. The Design and Layout Surface also allows for free movement, which can be a big advantage during the layout process.
