IRWINQUICK-GRIPOne-Handed Bar Clamp, Medium-Duty, 12", 1964718

I bought this set to jerry rig into fishing pole holders at the pier. Did not work for that purpose, but they are good clamps and I've had more of these. Again, I really did not need a pair, but there seemed to be no way to buy just one that I saw. I am very pleased by these clamps. They have a very positive and sturdy mechanism, and they develop more clamping pressure than those I've used in the past. They hold their set clamping force without the gradual slippage. All moving parts that are involved in producing and holding the clamping pressure are made from fairly heavy metal. The actual handles are plastic, and the actual clamping jaws seem to be made from a fiber-reinforced plastic of some sort, which are heavier built and apparently sturdier than other ones. The slip-on pads on the jaws are not the greatest, but they seem to do the job well enough. PRO: 1. Price per foot. 2. Brand. 3. Reputation. CON: 1. Lacks some of the 'kool' features a more expensive set would have. 2. Can't buy just one. 3. Plastic can snap over the years, but that plastic keeps the price down. OTHER: BUY if you want reliable product. DON'T BUY if you are wanting top shelf product, that'll cost ya more $$.

These clamps are great. Easy to use and they don't break. You only need one hand to clamp them, leaving your other hand free to line up the pieces. Great when you are working on projects alone. Not just for gluing stuff, these can give you extra hands while making decks, furniture, etc. You can level a board and then lock it in place, then go back and secure it with screws. Yes, you can buy some that look almost identical from other manufacturers for much less money, but these don't break. IE - I bought 6 HF clamps a few years ago, but they ALL broke in the first 30 seconds of use - not exaggerating. You will probably buy more of these, but only because they are so useful, not because they break. My oldest Irwin Quick clamps are 15+ yrs old and still working great. Only think to avoid is leaving them outside in the rain all week, as they will rust if you do, and then they don't work very well (but you can wire brush them back to life)

Versatile clamps that can be reversed to spread or lift items.

Works ok but a bit too pricey

While this was a Christmas Present for my son, I have used this sort of clamp for decades, and this is a quality clamp!

These have become my go-to clamps. They're so much easier to use than the old screw-on clamps, and they're lighter as well. I only revert to the old-style clamps if I have to clamp something for a long time. eg glueing.

Strong medium duty 6-inch clamp by Irwin. Very happy with these and have already ordered 3 more. Used these with some really heavy forces on the clamp and held up well. It was really easy to change the direction. Used to hold some 2x8" material and held the lumber fine for the project. Good size, strong and sturdy.

Sólidas y bien construidas.
