Micro Jig GRR-Ripper® Basic 3D Push Block System GR-100

Safer and more precise than conventional push blocks.

Item #
96% of 100

The GRR-Ripper is a precision-guidance 3D Push Block System designed to feed wood on a table saw more safely than you can with your hands alone, and more accurately than with conventional push blocks. The result will be better projects with intact fingers and less waste. With its 3-Directional control, it gives you downward, forward, and lateral pressure on the stock for maximum control and safety.

The GRR-Ripper's patented design eliminates the need for bare-hand feeding, since it essentially acts as a movable blade guard that travels with your hand, rather than being affixed to the back of the table saw, or one that hovers above it. The GRR-Ripper becomes an unyielding barricade between the table saw blade and both of your hands. Maximizing the use of your materials no longer has to compromise your safety. Aside from the safety, you truly get better cuts.


  • Results in a perfectly straight cut and safely keeps your hands away from the cutting elements.
  • With grooved, non-slip pads on bottom and adjustable handle.
  • Attachment kit (sold separately) consists of additional spacer and stabilizing accessory plate for extra control - ideal for narrow ripping.
  • Micro jig Handle Bridge (sold separately) provides four contact points to apply more downward pressure across the entire width of the Micro Jig GRR-Ripper's body for better control. Also includes replaceable push foot.
  • Micro Jig GRR-Ripper instructional DVD covers over 30 applications of the Micro Jig GRR-Ripper System on four different machines: table saw, router, jointer and band saw. 120 minutes.

Best accessory for your table saw
After one too many close call with the spinning blade, I finally get the Gripper. It performs wonderfully that wish I have it sooner. Would recommend to any one that work with the table saw.

Versatile tool
Comes in handy on the saw or router table. I was pleasantly surprised by the leveling fence---didn't think I'd need it as often as I do. The grip is exceptional, too, which makes my shop more safe.

whats the difference between the 100 and the 200, other than price ?
jimmy b b on Apr 17, 2015
BEST ANSWER: The 200 has a Stabilizing Plate that attaches to the Balance Support. It can be used as an additional Fence in some operations. Handy to have it when it is needed. I have Two GR-100's and One GR-200. That way I can have them set up for different functions while doing a project.
What width of timber can you cut safely?
Big k on Aug 29, 2015
BEST ANSWER: If you're question is "how narrow", then I would tell you that I've used them to cut strips of 1/32" for edge banding. And as importantly, never felt like I was in any danger of getting my hand into the blade.
How big is the package? A friend of mine will bring it to germany and I don't want to use up all his suitcase-space...
Marc S on Jan 26, 2016
BEST ANSWER: The Basic Unit is 7" w X 3 5/8" d X 5" h, and there is an extension piece that adds another 2" to the depth. But that is all neatly packaged. So the final Box may be 8X5X6 minimum. I don't have the packaging anymore so this is a guess. It could be 10 X 6 X 7(8) ??
My table saw comes with splitter, paws and a guard. Would I need to remove all of that to use the GRR-Ripper? Thanks my friends!
Christine T on Nov 20, 2015
BEST ANSWER: The gripper can be and should be used with all safety equipment in place, it is designed to be adjusted so you can pass over the blade if you need to. There are some cuts that you have to remove the safety equipment, but the gripper does not replace safety equipment.
Do these come with a heel kit or do you have to buy that separately?
Martin B on Oct 8, 2017
BEST ANSWER: Mine did not come with one. It would be nice to have one, but I have never used one. They are very grippy and push the stock without a heel. Also, I was told that the heel is sacrificial at times. So it might get costly.

That said. These are awesome. I bought one, used it and went right back to the store that afternoon and bought a second one. I can't recommend them enough. I never use my table saw without them now. There are tons of other uses for them also.
Will this work for freehand work on a router table?
Philip S. H on Feb 22, 2017
BEST ANSWER: I would say it would do a good job.
Ok, I see how it is great for making narrow cuts. What is the greatest distance you can have from the fence to the blade? If you wanted to rip say an 11" wide piece down the center, looks like you couldn't keep the gripper against the fence, correct?
Tom M on Aug 5, 2018
Maybe I don’t fully understand the question but it is good for any width of cut. In your specific example you would probably remove the extension plate as with it on I don’t think you will be able to make the cut do to its overall width. Remove the side extension plate and you’re in great shape to make the cut. I don’t always have the gripperbagainst the fence but I always use it to keep my board against the fence.
This is one of those aids I put off because I think what I am using is fine but when I finally bought it I was kicking myself for not having bought it sooner. Hope this helps.
