The world's safest pushblock
The GRR-RIPPER AIR ULTRA ’25 – Limited Systainer³ Edition is the most advanced pushblock system ever built, celebrating 25 years of innovation in woodworking safety. With all-new X-AIR Heels, a SafeRip Center Tunnel, and a complete arsenal of precision accessories, it delivers unmatched control on your table saw, router table, jointer, and bandsaw.
Packaged in a custom decorated Systainer³ Combi, finished in an exclusive anniversary green, and limited to just 1,500 sets worldwide—this is more than a tool. It’s a once-in-a-generation milestone in precision, safety, and control.
It all started in a garage in 1998, when Microjig’s founder Henry Wang asked a simple but radical question: “Is there a better way to make thin cuts while keeping my fingers safe?” That question gave birth to the original GRR-RIPPER, a tool that reshaped woodworking safety forever. Two million units later, used in workshops from Florida to Finland, the GRR-RIPPER has become a rite of passage for anyone serious about their craft. Now, to celebrate 25 years of innovation, Microjig is proud to introduce the GRR-RIPPER AIR ULTRA ’25 Limited Systainer³ Edition—our boldest leap forward yet.

Virtually eliminate kickback on table saws.
The X-AIR Heel automatically adds an extra heel effect at the end of your stock to augment the GRR-RIPPER's 3-directional force system. The GRR-RIPPER holds stock downward, inward and forward to maximize control and keep the kerf parallel to the blade reducing tool marks and the chance for kickback.
Kickback is the #1 cause of table saw injuries. A split second of lost control can turn a workpiece into a projectile—or worse. Kickback occurs when either side of your workpiece strays from the fence and gets pinched between the saw blade and the fence. The rear teeth of the blade grab the workpiece resulting in kickback.

Protect your hands during the entire cut.
- Center Leg
Adjusts to varying material widths, allowing you to control both the keeper and off-cut sides of your workpiece through the entire cut. - Balance Support
Adjusts to match material thickness, keeping the Grr-ripper® upright and square.\ - Adjustable Spacer
Gives you 54% more gripping surface for larger workpieces and provides clearance for exposed router bits. - Stabilizing Plate
Provides 250% more stabilizing surface and rear hook pushes the tailend of workpiece. Locks material parallel to the fence like a featherboard. - Green Grr-rip®
Treaded surfaces conform to your workpiece to provide incredible traction and control over hardwoods, composites, plastics, and aluminum
Create your own clamp tracks.
With MatchFit, you're not confined to pre-set clamp positions. Carve out your custom dovetail tracks on any wooden surface, enhancing your hold-down capabilities where you need them most. The Dovetail Track System gives you all the functionality of T-track, in less time and at a fraction of the cost.
Seamless dovetail integration: All MatchFit clamps slide into any 1/2" x 14º dovetail groove, transforming your setup into a unified clamping haven for unmatched efficiency.

AIR ULTRA Exclusive Upgrades
Whether you’re ripping thin strips, resawing on the bandsaw, jointing a face flat, or taming a router bit, the ULTRA gives you the stability, pressure, and precision the old push stick never could.

Organized and ready for action.
Custom Systainer³ Storage System – The 25th Anniversary Ultra '25 package comes in a custom printed Combi M287 Systainer³, perfect for keeping both GRR-RIPPER AIR units and all accessories organized, portable, and protected. Everything in its place, ready to roll from your shop to the jobsite.

The X-AIR Heels on every leg are built-in, auto-deploying heels that flex out of the way mid-cut and snap into place at the tail end for total control. Nothing to attach, nothing to lose—just safer, smarter cuts every time.

The SafeRip Kit enhances your GRR-RIPPER's safety features by preventing accidental blade contact with the Center Leg. The AIR SafeRip Cursor guides your setup, and features a cutout aligned with the SafeRip Center Tunnel.

The SafeRip Center Tunnel is a new passage through the Center Leg allows the blade to pass safely while keeping pressure on both sides of the cut. The included SafeRip Cursor protects the leg and guides your setup.
Complete precision, control, and safety.
The ULTRA ’25 adapts instantly. Think of it as an all-shop safety system: table saw, router table, jointer, bandsaw. X-AIR Heels give you grab-and-go simplicity, while Gravity Heels shine when you need dialed-in adjustability. Together, they redefine how one pushblock can master every machine in the shop.

ReSaw Riser Blocks
Exclusive riser blocks expand your capability on the table saw, letting you safely handle taller material and achieve resaw-level precision without losing control.

GRR-RIP ReNew Cleaning Station
Restore grip in seconds. A quick spray and wipe keeps the Green GRR-RIP material performing like new, year after year.

1/8" Leg
The 1/8” Leg allows you to rip thin strips down to a true 1/8” x 1/8" safely and repeatably. Make cuts other pushblocks can’t touch. Excellent for edge banding, models, or decorative inlays.

Gravity Heel Kit
The Gravity Heel Kit provides dynamic sacrificial heels that automatically retract mid-board, and drop down to hook the tail end of the workpiece. The specially material allows them to be cut, providing support to prevent tearout.

Handle Bridges + Deflector / Connector
The Handle Bridges distribute downward pressure evenly for greater control and safer cuts. The Deflector / Connector connects to the Handle Bridges and acts as a shield between your hands and spinning blades while deflecting chips and debris.

Rip without stopping or burning.
Two GRR-RIPPERs allow 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.
Use it around your whole shop.

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 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.
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 top. 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.
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.
What is the widest board the GRR-RIPPER will cut on a table saw?
Please click to watch the video for cutting wider stock. Download Instructions
How does the SafeRip cursor work?
Once your rip fence is set to the desired cut, simply adjust the Center Leg of your GRR-RIPPER so that the measurement you are cutting is NOT underneath the orange cursor on the GRR-RIPPER that is facing you.
For example, if your rip fence is set to 1-1/8” (29mm), the 1-1/8” (29mm) mark on the back of the GRR-RIPPER should be to the right of the orange cursor.
The cursor automatically accounts for the blade width and works on both side of the Center Leg, so when making a 2-1/2” (64mm) rip cut, the 2-1/2” (64mm) mark should be to the left of the orange cursor and the blade will pass safely to the left of the Center Leg.
