The MICROJIG RR-303 Replacement Leg Set is the factory three-piece spare-leg kit for GRR-Ripper 3D pushblocks. Each yellow leg drops into the same slot as the original equipment legs on a GR-100, GR-200, or GR-281 and lets the operator extend the working life of a pushblock that has worn legs from heavy ripping or accidental contact with a blade.
The 3-piece configuration covers the front, middle, and rear leg positions of a single GRR-Ripper or refreshes one position on three blocks. Replacement legs are the recommended consumable in the MICROJIG safety system — when a leg gets nicked by a blade it should be swapped out so the block still applies even pressure to the workpiece. The yellow molded plastic matches the production GRR-Ripper shells and threads into the same captive nuts that hold the originals.
MICROJIG manufactures the RR-303 leg set in Winter Park, Florida — Made in USA per the manufacturer’s listing. Keep a spare set on the shop bench so a damaged leg never sidelines a GRR-Ripper mid-project, and pair the RR-303 with a GRP-11G 1/8-inch thin-rip leg when you need to handle very narrow stock.
