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 (1/2")

Heavy duty. Works well. Good quality

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.

I am an amateur woodworker who sometimes builds cabinets and furniture. I needed more stout clamps than the F clamps I had. I needed longer clamps than the F clamps I had. I needed more clamping power than the ratchet clamps and F clamps to wrangle strips of dimensional lumber into flat straight glued planks.I bought 8 name brand 3/4 inch pipe clamps and pipe locally. They worked great. I needed more though, so for less than half what I spent on name brand I ordered 8 of these clamps. The colors are different, who cares. The screws are chrome instead of some high tech stuff, no big deal. Clamping power is near identical.So why only 4 stars? The threads for the pipe are less than satisfactory. I have had to swab every clamp with a wire brush before the pipe threads would even engage. I also had to massage the sides with a mallettoget the pipe to thread most of the way in. After a couple assembly/disassembly cycles the clamps function acceptably well.Will I buy more if I need more? Yes, probably. The price for performance is excellent, with the fit being annoying but easy to overcome. I have chosen 3/4 inch pipe so I have enough of a starting stock of pipe that changing sizes would be an unnecessary expense.

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.

Good for my needs. Well satisfied

Worked as I hoped they would. Used them already. Good buy for a good product

Poor quality. But they work.

Nice and affordable clamps for beginners and experienced wood workers. Depending on the price of your local pipe suppliers the final cost will be twenty five to thirty five dollars for a 48 inch clamp.

Buy them if you need them work awesome.

Este es un excelente producto al mejor precio al que lo he encontrado tiene la gran ventaja de que puedes hacerlo al largo que tú quieras siempre y cuando cortes el tubo, si estás en mexico en casi cualquier tlapalería te pueden hacer la rosca para que puedas instalarlo

Not worth it. Find a good quality at the hardware store. I broke one and the remaining three getting stock and need a hammer to get them loose

Muy buenas prensas solo hay que tener en cuenta que el tubo a usar tiene que ser al menos cedula 40 o barra solida. Cualquier cosa de menos calibre provocara el rompimiento de la rosca.

Threads under wheels are easy to damage even with low tight
