Microjig GB-1 GRR-Rip Block Smart Pushblock is designed to provide an extreme grip on your workpiece, making it an essential tool for safer and smarter woodworking. Inspired by the renowned GRR-Ripper, this pushblock excels at the table saw, band saw, router table, shaper, or jointer. It features Microjig’s highly grippy, podular green non-slip pad combined with innovative Gravity Heel technology. The Gravity Heel hooks automatically drop down to securely grab the end of the workpiece and flip back when not needed, working efficiently both horizontally and vertically. A unique snap mechanism even allows you to lock the heels completely out of the way if desired. The block’s generous size of 9 inches long by 3-1/2 inches wide, along with its ergonomically angled large handle, ensures comfortable and precise control. Additionally, it includes special inserts for adding Microjig’s optional Deflector Connector (sold separately). Using the GRR-Rip Block enhances stability and control, resulting in improved accuracy and a more enjoyable woodworking experience. It works well individually but performs when used in pairs. Made in the USA.
