Precision, Control, & Safety

Support your workpiece and prevent tearout.

The Gravity Heel Kit includes 5 dynamic heels that auto retract mid-board, and drop down to hook the tail end of the workpiece. The specially formulated plastic material allows them to be cut, providing support to prevent tearout at the end of the cut.

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 ABS 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 cut into my GRR-RIPPER, now what?

Every part of the GRR-RIPPER is individually replaceable, and compatible with all GRR-RIPPER models. Browse and swap out any damaged part with a replacement.

Will the GRR-RIPPER trip the sensor on my Sawstop?

No. The plastic material will not trigger the safety mechanism on Sawstop saws.

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.

My GRR-RIPPER doesn’t seem as grippy as it used to - what gives?

Over time, dust and other contaminants can build up and compromise the effectiveness of the Green GRR-RIP material. Cleaning the gripping surface with denatured alcohol should restore your GRR-RIPPER to its original glorious grippy-ness. In rare cases, prolonged exposure to sunlight can damage the gripping material, so keep it out of direct sunlight.

Will the GRR-RIPPER work on my table saw?

It will work on any standard table saw with a fence and a blade.

Can I use the GRR-RIPPER with the blade guard on my table saw?

The GRR-RIPPER passes over the blade so there can’t be anything in the way. Don’t worry, the GRR-RIPPER is your moving blade guard.

Why would I need two GRR-RIPPERs?

We recommend using two GRR-RIPPERs when cutting stock longer than your table saw top.  In order for the GRR-RIPPER to work properly, it needs to be on top of the material, with the material on the table stop.  If you stop feeding material to reposition your GRR-RIPPER, the saw blade will leave blade marks and burning. With two GRR-RIPPERs, you can feed stock continuously using the hand-over-hand method, resulting in better cut quality.

How do I use the GRAK-404 Upgrade Kit for the GRR-RIPPER?

Here’s a short video showing many of the great uses for the GRAK-404 Upgrade Kit AKA the Stabilizing Plate and Adjustable Spacer.

Can I use the 1/8" Leg with the GR-100?

Yes! In fact, the 1/8″ Leg fits all existing GRR-RIPPER models.

I have missing parts for my GRR-RIPPER, what do I do?

We’re so sorry about that. Please call 1-855-RIP-SAFE (747-7233) or contact us here with the missing parts and the quantity you need.

Where can I buy the GRR-RIPPER in Australia?

Please take a look at our Find a Retailer page and scroll to the bottom and click “International Retailers” to see a list of our Australian dealers near you. Many outside retailers also offer shipping to Australia.

Is the GRR-RIPPER OSHA compliant?

Yes. OSHA regulations state that “...​in a workplace, regulations require that unsafe saws be removed from service immediately, push sticks or push blocks be provided at the work place for guiding or pushing material past the blade, and emphasis be placed on the cleanliness around woodworking machinery and, in particular, the effective functioning of guards and prevention of fire hazards. 29 CFR1910.213(s)
