Those remind me of some I have that I call my Caulking gun clamps. Got em at Odd Lots years ago for 50 cents apiece. Not the finest clamp in the world, and mine are just the clamp. Yours seem to have a variety of accessories. Just what I need clamps that have accessories, like clamps aren't expensive enough already.

Now for squeeze handle clamps IMHO there are none better than the Jorgies seen here, and I find the 12" the perfect size to have a big pile of.



The other smaller clamp I dearly love, and just really wish I found about them BEFORE I spent so many dollars on Bessey gear clamps are the Jorgies seen here.



Both of these things for the price, as compared to prices of other name brand clamps are much stronger, and do such a better job, I can barely describe.
