Review of Irwin 224134 Quick-Grip 3/4-Inch Pipe Clamp

The few negative reviews here about the clutches being installed backwards almost kept me from buying these, but I decided to give them a try anyway since intuitively it seemed that the clutches and spring must be user serviceable.They arrived a day ago and I just got some black iron pipe for them to check fit and operation, and I must say I am very impressed with these clamps.The fit is tight and precise, the screw turns easily without binding, and the sliding jaw moves easily along the pipe.Cosmetically they are much nicer than any other I have seen in stores.The clutches on mine were all installed properly -- however, had they been installed in any other manner I could have simply compressed the spring by hand, removed the clutch plates and reinstalled them in the correct orientation!No problems there (I tried it and verified that if installed upside-down they will cause the problem mentioned in previous reviews, but as I said this is easily fixed).I bought these because of the extended height of the feet, which do allow knuckle clearance when operating the hand screw.The feet seem to be wider also, making these more stable.One thing I did notice is that the entire screw length can not be used due to the handle butting up against the end of the clamp when tightened all the way (maybe an inch of unused threads) but this is trivial -- there is plenty of thread length to do the job.I bought four sets of these for some furniture building projects I am working on, and will buy more in the future!The only things this clamp does not have vs. the Rockler ones is the lip on the threaded foot for hanging on a rack, and pre-drilled holes for mounting extention blocks.I plan to take a 2x4 and cut some notches in it so I can simply slide the pipe into the notch with the threaded jaw resting on the top for easy hanging, and if I ever need to mount anything to the jaws I can drill the holes easily enough.I do like the fact that the pipe does not have to be threaded, although the pipe I bought has threads cut and it works great.If you're looking for a high-quality pipe clamp buy these!Feel free to email questions to me (just remove the "nospam" from the address).
