How it works.

GRR-RIPPER Upgrade Kit (For GR-100)

Three directions of force.

Three directions of force provide essential stability for superior precision, safety, and control.

  • Downward pressure stabilizes work piece on a flat surface.
  • Inward pressure against the fence virtually eliminates kickback.
  • Forward pressure feeds stock consistently through the cut to eliminate burning and blade marks.
GRR-RIPPER Upgrade Kit (For GR-100)

Virtually eliminates kickback on table saws.

Kickback occurs when the workpiece strays from the fence, and gets pinched between the saw blade and the fence. The rear teeth of the blade grab the workpiece, turning it into a dangerous projectile. The only way to avoid kickback is to maintain control of your workpiece through the entire cut.

The GRR-RIPPER® provides downward and inward pressure, keeping both sides of the cut parallel to the blade. This prevents the workpiece from straying from the rip fence, virtually eliminating kickback.

Rip without stopping and burning.

Using two GRR-RIPPERs allows you to feed long stock continuously without stopping, virtually eliminating burning and blade marks caused by inconsistent feed rate. Parts come off the saw ready to use with little to no additional sanding or planing.

Over 30+ uses on table saws, router tables, jointers, and band saws.

Table Saws

The GRR-RIPPER was built for the table saw. It acts as a moving blade guard, shielding your hands from the saw blade through the entire cut. Right out of the box, the GRR-RIPPER can cut stock down to ¼” x ¼”. Because it provides 3 directions of control, your cuts will be cleaner and more precise.

Router Tables

The GRR-RIPPER provides incredible command over your workpiece on the router table. Whether you’re using the fence or freehand routing, its powerful grip controls stock and protects your hands from dangerous spinning bits.

Jointers

The GRR-RIPPER’s proprietary Green GRR-RIP material provides all the traction you need to properly flatten stock on the jointer. Because of its powerful grip, you can feed material over the cutter head without having to apply too much downward pressure.  The GRR-RIPPER makes proper face-jointing technique easy, and safe.

Band Saws

The GRR-RIPPER's legs and main body maintain a constant 90 degree angle. It can be used on its side which is ideal for resawing on bandsaws. The GRR-RIPPER glides along the table top and applies even pressure against the fence with your hands clear of the blade. Even pressure means less blade drift, resulting in smoother cuts.

Got questions?

Why plastic?

The GRR-RIPPER is made of specially formulated high-impact plastics for good reason. It maintains its shape and rigidity, but also absorbs force if it makes contact with the blade. In other words, it won’t shatter or break your wrist.

I have a GRR-RIPPER with black parts - will yellow replacement parts fit?

Yes - the design is exactly the same. Black and yellow GRR-RIPPER parts are interchangeable.
