Reviews for "90° Corner Clamp"

Thought Clamp was broken but

The clamps did not work from the start, so I contacted Kreg. They responded the same day explaining how to reset the automaxx system on the clamps. They are not working like a charm. I will share the instructions on how to reset the automaxx system, as I could not find them in the FAQs. So you will open the jaws and back out that adjustment screw to the point where it is really loose but not falling out. You should see around 3/8" of threads between the bottom of the head of the screw to where it screws into the mechanism. Then you will close the jaws then open them back up. After that, you can bring that adjustment screw back to the positive around halfway down and try to clamp it down. That adjustment is not an exact adjustment, you may have to tighten it more or loosen it more to get the correct pressure you want to apply. When you are using the clamp, you will want to make sure you are opening the clamp fully when you are moving the clamp. This will allow the Automaxx system to reset to zero each time. You should only need to adjust the adjustment screw if you need to add or take out pressure from the clamp as the clamp will adjust to different thicknesses on its own.

Adjustment Screw

Looked like a great tool, unfortunately could not get the adjustment screw to work and lost time on a project because I had to take it back to store to get my money back. Fix the adjustment screw and this will be a really great tool.

Great Product

I also found the adjustment knob a little hard to use, could be a little bigger, but overall everything else about this clamp makes that almost a non issue. I've used this clamp on two projects already and in both instances it worked great and setup time was considerably faster than other methods I've used in the past. IMO, Kreg has a real winner in this clamp.

Very useful tool!

I really appreciate those notches cut into the clamp so I have access to screws without removing the clamp. Also excellent quality product, Kreg you did it again!

Adjustment knob

Haven't used yet but while checking out the tool I found it very difficult to turn the adjustment knob.
