GRS 003-651 MicroBlock Short Jaw Kit

Reduce the working height of your GRS MicroBlock or GRS MicroBlock XL by 9.5 mm by replacing the standard jaw set with this short jaw kit. Designed as a direct drop-in replacement, the short jaws share the same pin holes and thread pattern as the standard MicroBlock jaws, making the swap straightforward with no modifications required.

The reduced profile is especially useful when working under a microscope, where gaining even a small amount of vertical clearance can meaningfully improve your line of sight and tool access. The short jaw kit is also well suited for use with the Alexandre Ring Fixture and ID Ring Holder, providing a lower grip position that complements those accessories.
