IRWIN QUICK-GRIP 1964758 One-Handed Mini Bar Clamp 4 Pack, 6"

Imperative item to have as a second pair of hands. Brilliant device. Works well with workmate bench.

Excelente opción, las recomiendo 100%. Tienen bastante apertura, se sienten de buena calidad, son compactas. El único detalle es que solo sirven para apretar, a diferencia de otros modelos que pueden servir para abrir o levantar.

Abrazaderas de fácil uso, robustas y con muy buena calidad como corresponde a una marca como Irwin. Cumplen con lo que esperas de ellas.

These are the nicest clamps I've ever had! They are quick and easy to use. Can be applied with one hand while holding something together. The clamping force is very strong. I've been using a pair of these for the last year or so in my new workshop and I don't know how I got along without them! It's like having an extra pair of hands to hold pieces together while drilling holes and putting in screws. I just got through putting together a workbench using the 4X4 Basics Work Bench Kit and a set of shelves on it with the 4X4 Basics Shelf Links system. I never would have been able to get it all together without being able to use these clamps to hold things while I drilled and screwed pieces together. With the rubber caps on the clamping faces I didn't have to worry about marking the finish on the pieces either like the old pipe clams or big C clamps would. And they are a lot easier to apply and remove one handed which is very difficult to do with pipe clams and C clamps. Before building my workbench I used them while putting together a 10'x10' Barn Style Storage Shed from a kit that I got from Lowe's. These things helped so much I got almost the entire project done by myself only needing help standing up the walls and decking the roof. I also used them when building several sets of shelves with the 4X4 Basics Shelf Links for my shop and storage building. And even for that these held things together for me while putting in the screws. (I used screws for almost everything that was usually done with nails) After a year of use they still work flawlessly. I like them so much I had to order this 4 pack. Now that I got them my only complaint is that I didn't order 2 packs of them instead of just the one! Since I'm retired after being a machinist for over 25 years I have a thing about quality tools, and that's what these are. They are well made and work like they are supposed to. I highly recommend these clamps for anybody's workshop. UPDATE 11/2/12 Well, now that I'm getting into using the workshop I spent the last year building and tooling up I'm now ordering another 4 piece set of these clamps. I forgot to add before that I was a little worried about these being made of,, you guessed it, plastic. But the four piece micro clamp set and the 2 piece 18" pair I got have held up under the heaviest use and the most clamping force that I can put on them. Which with my big hands, & since I'm 6'4" and 240 pounds I have pretty big hands and a very strong grip, so I can put a LOT of force on clamping these. I think they would even hold up if you used one clamp to squeeze down the clamp on another one. So again I can highly recommend these for anybody that has a workshop. Anything from your kitchen table to a small area in a back room, or a closet in a bedroom turned into a work space, or a full basement or garage workshop, and up to a full sized manufacturing company with a building covering 10 acres. Like the Halliburton shop I worked in in Duncan Oklahoma back in 1981 to 83. You need several pairs of these!

I used them alot, good value for the money.
