GRS 003-674 Step Riser For Microblocks

The GRS microblock stands 3.375" tall when placed on its plastic base. Use this set of 5 risers to adjust the height of your microblock. Using a single riser will raise your block up approximately 3/8" (9mm). Using additional risers will raise your block approximately 5/8" (15mm). Using a single riser only raises the block 3/8" because of the concave center of the riser. Use all five risers and your block is raised approximately 2-1/2" (63mm). Using the risers makes it easier to adjust your working distance when you are using a microscope. The new GRS Microblock™ Ball Vise is the latest product in a broad line of precision work-holding tools. Like larger GRS vises, the Microblock is machined from solid stainless steel and finished with a special low glare treatment to reduce eye strain. This new vise was designed for a unique combination of solid work support in a small and maneuverable size. The smooth self-centering jaw system is perfect for stone setting, small engraving jobs and other precision work. An adjustable internal brake system lets the user choose the amount of rotational resistance from totally free to fully locked and anywhere in between. The Microblock’s low profile and compact design is especially suited for microscope work or other situations where the size of a larger vise is an obstacle. Included with the microblock is the support base, 2 sticks of thermlock, 6 hex nuts, 4 holding pins, and 2 hex keys. The working surface is oval shaped and measures 40mm x 43mm. This microblock contains the attachment set. The GRS Microblock weighs 4 lbs (1.8kg) with a ball diameter of 3.1" (80mm) a jaw width of 1.8" (46mm) and a jaw height of 0.87" (22mm). The maximum diameter opening of the jaws is 2" (50mm).
