Great little clamps! 08/23/2020 1:04:18 PM

I was looking for clamps I could set in place on the T-track and then easily and quickly clamp and release repetitively with plenty of space to move parts in and out. Oddly, They came set up for any position other than actually in-line with the T-track. With very minor modification, they work great, but when tightened down, they are a little close to the work surface, causing a little more friction than I was hoping . Not perfect, but much better than anything Ive tried and you cant have them back! Definitely high quality.

I received a grizzly t track table as a present for Christmas from my son. Typical t bolts from other clamps were too fat to fit so I ordered grizzly clamps. These did not fit either so I had to grind them. Very annoying. I would return the table if I could and buy a ticket or make my own. Not only did they not fit, they do not hold the material down tightly.
