It also adds one inch of cutting width to the GRR-Ripper. Also, acts as a secondary balance support for small stock and straight-line ripping. Great add-on for working on the Router Table, and eliminating snipe. - The Stabilizing Plate - The Stabilizing Plate adds a new dimension of control to the GRR-Ripper. It is particularly useful when cutting small narrow pieces of stock. Perfect for trickier cuts like resewing, bevel edging, pattern routing, and much more. - The Stabilizing Plate also performs as the secondary fence that travels with the GRR-Ripper along the left side of the stock. It holds the off-cut piece in its original position through the entire cutting operation. Without binding the operation, it provides enhanced stability over the cut and superior guidance along the fence. Made in the USA. A true MICROJIG Innovation. 100% Satisfaction .
