FLK Tech 4 Pack Wood Gluing Pipe Clamp Fixture for 3/4 Inch Pipe, Heavy Duty Pipe Clamps, Cast Iron Wood Clamps Quick Release for Woodworking, Carpentry, Home Improvement, and DIY Projects

The construction of these are very rugged and very easy to use. Although these are for wood glue ups, I use these for welding. Im able to easily clamp frames together and know that they will not move when making my weld. They have enough clamping force that I'm able to take about a 1/4" bow out of material by turning the lever with little effort. Great buy, I've bought a few sets of these already.

Heavy duty. Works well. Good quality

Great lower cost alternative to name brand pipe clamps. Obviously there are some minor flaws in casting, but they are 100% aesthetic. They clamp hard and hold well. They hold easily on the 3/4" sched 40, and no problem threading them on. Offer about the standard amount of adjustment in the clamp operation.

Nice clamps installation on a three-quarter pipe had others but these are better

clamped multiple cutting boards together and cranked very tight. No issues.

Good price, and clamps do work, although somewhat difficult to release and slide. The main problem is that the release protrudes well past the flat area on the back of the clamp. so clamps cannot rest on the tabletop with the opening oriented upward to accept the pieces to be clamped.

I bought two sets of these clamps, and while they aren't "Jorgensons", they do the job just fine for my small hand tool shop. A few arrived assembled 'backwards' but once I figured that out, no problems. They are just a bit 'sloppy' and the screws appear to be Acme threads... and they're close enough for the kind of work I do. I want to stress that the price CANNOT BE BEAT ANYWHERE!! Especially in these times of exhorbitant prices, it's the way to go for small makers and shops on a tight budget. I'd buy another set again if I needed more clamps, for sure.

Having extra pipe clamps available are such a versatile tool.
