Have used the Clamp-Its that came with the small bar clamps for years and they were a pain to set up to say the least. These with the universal clamps are much easier to use...not perfect, but a lot easier to use. Because they are on sale, it is cheaper to buy the whole system rather than just the clamps to convert any existing Clamp-Its I have. Once Rockler has a really good sale on the universal clamps I will convert all that I have and donate the worthless bar clamps they came with.

 This clamp is useless. It slips and won't cinch down. The problem is that the strap isn't positively secured to the capstan.

As usual for a Rockler new product it raises the bar for everyone in the category. These clamps work very easily and the adjustment mechanism is great.

I got these the other day and have used them Love them . was useing a board to do my straight liineing for cutting . These have saved me time at lining up . Wish I had gotten them a long time ago . Just line up the marks with one hand and tighten up with the other .

Found it not very useful.
