About 4 months ago I purchased the Bessey 30 piece clamp set and while they are good for clamping down things,ect. they are not made for gluing up large cabinet sides,ect. I was at Menards and purchased 6 of these Jorgensen 50 3/4" pipe clamps because after doing a lot of reading and reviews these might be a couple dollars more than the Chinese knok-offs, but now I know why. (My Chinese knock-offs were sold on ebay---they are junk!)These clamps are surpurb at gluing up stock, ect. After purchasing the 6 at Menards(because they were on sale for 8.99 each), the very next week I purchased six more from Amazon.com at 9.99 each with free shipping and no tax! I now have a total of 12 five ft. clamps and would not trade them for the world! These things are great but I would suggest either making a pad or purchasing the pads tor the insides of your clamps to protect you wood as they will mar up sides of glued lumber with enough pressure.
