clamp fits even thick concrete tables

I am thoroughly pleased with this umbrella holder.  It is very sturdy.  The clamp is wide enough to accommodate the concrete tables in the national park areas.  I had people stop at my campsite to find out what I was using to secure my umbrella since there were no holes in the tables. Note that the opening for the pole that holds the umbrella is large and held my market umbrella. There is a screw that secures it down.  The screw was too short for my sport/beach umbrella.  I ordered a second holder so that I can secure a tiki torch. I think this is a product is designed well.

Mine arrived in perfect condition.  This clamp is very well made and worked just like I had hoped.  Jorgensen makes a nice product here, and this type of clamp is really useful for many jobs around your wood shop.  I purchased this one to use with the Incra I-box jig (reviewed separately) that I got to make box joints, and it is a must for that application.  This type of clamp has many other applications too, so as a relatively novice woodworker I plan to buy more of this type of Jorgensen clamp in various sizes.

These bar clamps are excellent quality.  I have purchased them in several different sizes in the past.  The soft clamp faces and one-handed operation make these clamps extremely versatile and a pleasure to use.  The only issue is the shallow depth of the grip (how far into the surface of a piece can you grip).  In this case, only about 2 inches.  The buy 2 for the price of 4 deal was as good as any price I have found.

I bought tis clamp to use on my drill press, but I think it's going to be a good portable clamp that I can use on my workbench as well.  It's heavy enough to stay still while I use a dremel tool to shape an aluminum angle . The only reason I give it 4 instead of 5 stars, is the amount of 'slop' in the threaded rod and clamp.  Still a good buy.

Very heavy duty clamp rack does what it's made for.  Add some 1/4" lag screws for installation and you're good to go.

I'm pretty sure these would work great for some tables, but they didn't work on my table. The edge of the table is too thick and the clamp doesn't open wide enough. The table top probably shouldn't be more than 1 1/4" thick for these to work. They appear sturdy though.

This was the right size clamp to hold together a broken chair leg while allowing wood glue to dry.  I used it on a standard sized chair with standard wooden legs.

Rock-solid clamp, and the ball-heads stay put when locked. Perfect for attaching a speedlight to strange places. In my case, I combined it with velcro straps and a link of chain to attach one to the center pole of a wedding reception tent, and it worked brilliantly.

The biggest improvement I wish for is an angle clamp that could also apply pressure to the joint.  As it is, this clamp is like having an extra pair of hands to hold things in place while you fit bar clamps in place, drive nails or screws, etc.  I have found it extremely helpful to have four of the things, so I can have all four corners of a box or carcase held in place and all on the same level.

These are great clamps!  I used them to install a wire kitchen shelf system on a hollow door.  They worked great!

Very happy with this clamp.  My husband was equally as happy to receive it for a Christmas gift.  Well made and reasonably priced.

I only had 3/4-inch pipe clamps before, but I like the lighter weight of these 1/2-inch clamps for wood working.  They are plenty strong enough for most wood gluing operations, especially since many people clamp glue joints too tightly.  (All you want is intimate contact between the two surface and a little squeeze out all around.)  It is much better to use more clamps with lighter pressure on each clamp than to not have enough clamps and then need to really squeeze the joint hard with a few clamps.  Too much pressure can actually squeeze most of the glue right out of the joint and leave you with a weak glue line.  These economy clamps are a good solution for having more clamps on hand when you need to glue a long joint.  The quality is a little rough.  The threads  are poorly cut.  I could force the pipe threads but I was lucky enough to have a 1/2-pipe tap on hand to chase the threads.  I have had none of the problem with the dogs sliding on the pipe.  Maybe that happens when asking the clamps to handle too much pressure.  The bench-standing feet on these clamps really are useful at times.  For the pipes, I just went down to Home Depot and bought a 10-foot length of galvanized pipe.  The Home Depot guys will cut it into four equal lengths and thread it for you for FREE.  Four stars because of the marginal quality, but still a good value in my opinion.  These make a much better clamp than the cheap import bar clamps.  For good quality 24-inch bar clamps check out the on-line price of the Jorgensen 3724HD at the place with the initials that are the same as Heavy Duty.  I have both, and these Bessey pipe clamps are for when 24-inch reach isn't enough.

These clamps are great.  They even hold items with large handles.  Easy to release too, only need one hand to do so.

Weird mix of all metal frame and screw with a PLASTIC turn handle and clamp ends. The only plastic should have been the replaceable pads on the clamp ends. There are no instruction included so you need to decode the box. Removable non mar pad is a duplicate of the plastic non mar pad under it.  Screw holes in the bracket let you increase clamping strength up to 850lbs of force. Love that you can add these to any 2x4 to create a super long clamp. Just buy more than one. Wish they included a tote bag for folks taking them to job sites. Overall happy with the purchase.

I already had a set of 12" and 24"  Wolfcraft bar clamps. I bought the 6" because the bar got in the way using the longer sets on some of the glue up jobs I'm doing. Wolfcraft has a better grip pressure than the other clamps I own.

This clamps are awesome. They're sturdy and heavy and the grip is big even for big hands. Superior quality.
