{"product_id":"grs-step-riser-microblock","title":"GRS 003-674 Step Riser For Microblocks","description":"\u003cp\u003eThe Step Riser Set lifts a Microblock vise off the bench so you can set working distance to suit your posture or your microscope. Made by Glendo GRS as part 003-674, the set gives jewelers, engravers and stone setters five risers that stack in combination to reach the precise elevation the job needs.\u003c\/p\u003e\n\n\u003cp\u003eThe GRS Microblock itself stands 3.375\" tall on its plastic base. Adding a single riser raises the block approximately 3\/8\" (9mm) because the concave center of the riser accounts for the modest gain with one unit. Each additional riser added raises the block approximately 5\/8\" (15mm). Using all five risers together raises the Microblock a total of approximately 2-1\/2\" (63mm), providing meaningful height adjustment range for any workbench setup.\u003c\/p\u003e\n\n\u003cp\u003eThese risers are purpose-built for use with the GRS Microblock™ Ball Vise, a precision work-holding tool machined from solid stainless steel with a low-glare finish to reduce eye strain during detailed work. The Microblock features a smooth self-centering jaw system, an adjustable internal brake for variable rotational resistance, and a compact low-profile design optimized for microscope work and precision tasks such as stone setting and small engraving jobs.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSet of 5 stackable risers for incremental height adjustment of GRS Microblock vises\u003c\/li\u003e\n\u003cli\u003eSingle riser raises block approximately 3\/8\" (9mm) due to concave center design\u003c\/li\u003e\n\u003cli\u003eEach additional riser adds approximately 5\/8\" (15mm) of height\u003c\/li\u003e\n\u003cli\u003eFull set of 5 risers raises Microblock approximately 2-1\/2\" (63mm) total\u003c\/li\u003e\n\u003cli\u003eDesigned to improve working distance and ergonomics during microscope use\u003c\/li\u003e\n\u003cli\u003eCompatible with the GRS Microblock™ Ball Vise system\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eNotes\u003c\/h3\u003e\n\u003cp\u003eWhat you get:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e5 step risers for GRS Microblock\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe single riser raises the Microblock only 3\/8\" rather than 5\/8\" due to the concave center of the riser.
