The GRR-RIPPER AIR ULTRA '25 – Limited Systainer³ Edition is the most advanced pushblock system ever built, celebrating 25 years of innovation in woodworking safety. With all-new X-AIR Heels, a SafeRip Center Tunnel, and a complete arsenal of precision accessories, it delivers unmatched control on your table saw, router table, jointer, and bandsaw. Packaged in a custom double-stacked Systainer³, finished in an exclusive anniversary green, and limited to just 1,500 sets worldwide—this is more than a tool. It's a once-in-a-generation milestone in precision, safety, and control."It all started in a garage in 1998, when Microjig's founder, Henry Wang, asked a simple but radical question: 'There has to be a better way to make thin cuts and keep my fingers safe." That question gave birth to the original GRR-RIPPER, a tool that reshaped woodworking safety forever. Two million units later, used in workshops from Florida to Finland, the GRR-RIPPER has become a rite of passage for anyone serious about their craft. Now, to celebrate 25 years of innovation, we're proud to introduce the GRR-RIPPER AIR ULTRA '25 Limited Systainer³ Edition—our boldest leap forward yet.New Features:X-AIR Heels on Every Leg: Built-in, auto-deploying heels that flex out of the way mid-cut and snap into place at the tail end for total control.
