The Microjig® GRR-RIPPER® is a revolutionary, universal pushing jig for all table saws, router tables and jointers. It’s the first tool that grips and holds both sides of a workpiece during a ripping operation. Unlike a push stick or push block, the GRR-RIPPER® maintains balanced pressure on a workpiece as it passes through and beyond the blade. It allows you to maintain a parallel, forward direction with the blade while keeping pressure against your rip fence, which prevents burning. It also eliminates the need to feed stock with your bare hands, providing 100% protection. With this system, you can cut strips as thin as 1/4" without any unique setup, which means throwing away those small scrap pieces is unnecessary. You can also offset the unit to accommodate small, irregular-shaped pieces on the router table.The GRR-RIPPER® PRO boasts all of the same innovative features as the GR-100+, plus two additional accessories: the Adjustable Spacer and the Stabilizing Plate. Together, these accessories improve the control and expandability of the GRR-RIPPER® System. The Adjustable Spacer adds an increased gripping surface for tackling larger stock. It adds one inch of cutting width to the GRR-RIPPER® and is a secondary balance support for small stock and straight-line ripping. The Stabilizing Plate improves control of the GRR-RIPPER® when cutting small, narrow stock. Perfect for trickier cuts like resawing, bevel edging, pattern routing and much more. The Stabilizing Plate also acts as a secondary fence that travels with the GRR-RIPPER® along the left side of the stock, holding the offcut piece in its original position through the entire cutting operation.The GRR-RIPPER® PRO now includes the SafeRip Kit, making it easier to line up cuts and avoid accidentally cutting the center leg or the GRR-RIPPER® itself. This innovative kit enhances your safety and cutting control with a cursor that indicates the position of the GRR-RIPPER's center leg, allowing for precise adjustments. When the orange cursor covers your desired rip width on the SafeRip scale, you can easily reposition the center leg for perfect alignment. The SafeRip Kit attaches effortlessly, providing instant improvements in safety and control. Once installed, the SafeRip Index is a reliable guide for achieving flawless cuts—offering straightforward, dependable performance for all your woodworking projects without the need for complicated adjustments.Features:Eliminates the need to feed stock with your bare handsAllows you to make precision ultrathin cutsUniversal pushing jig for all table saw, router table and jointer usersHolds both sides of the workpiece during a ripping operationDownward pressure stabilizes the workpiece on a flat surfaceInward pressure against the fence virtually eliminates kickbackForward pressure feeds stock consistently through the cut to eliminate burning and blade marksIncludes the Adjustable Spacer, Stabilizing Plate and SafeRip KitWhat's Included:(1) GRR-RIPPER+ 3D Pushblock(1) Adjustable Spacer(1) Stabilizing Plate with Balance Support(1) SafeRip Kit(1) Instruction Manual
