The MICROJIG GB-1 is a GRR-RIP-BLOCK smart push block that delivers downward, forward, and inward pressure simultaneously through three contact zones — protecting the cut from kickback while keeping fingers safely above and behind the blade. The patented adjustable design adapts to varied stock thicknesses for safer cuts.
Use it on table saws for ripping narrow stock, router tables for shaping work, band saws for resawing, and jointers for face-jointing. Woodworking shops, cabinet makers, and DIY enthusiasts use the GRR-RIPPER as a daily safety standard around stationary blade-and-cutter tools.
MICROJIG manufactures all GRR-RIPPER pushblocks in Winter Park, Florida. The brand has been making woodworking safety products in the United States since 2002.
