4.0 out of 5 stars Great for Woodworking, August 13, 2000

This review is from: Quick-Grip Quick Change 550QC 50-Inch Bar Clamp/Spreader (Tools & Home Improvement)

I bought two 50inch and two 24 inch for a series of wood projects. I found them to be easy to use and extremely strong. I mostly used them for glueing up wood together and could really bear down and watch the glue get pushed out between the joints. I could not get that with other clamps.

The only thing to watch out for, is the pressure might make marks in soft wood, so I would use a 1 x 2 in between the project and the clamp, to distribute the pressure.

4.0 out of 5 stars An Extra Set Of Hands, December 3, 2002

The quick change is very helpful for various tasks. The only problem I experienced is that the Quick Change side(reversible side) contains plastic clips. Mine broke. I had to buy a second just to make it useful again. keep in mind how much pressure you apply and make sure the clip is fully engaged befofe using the tool.

The big benefit to these is that you get true mobility out of them. While holding a piece of work, lined up, in one hand, you use these quick grips in the other hand to secure the work. If it slips while clamping, it is still a one handed tool to release it, and reclamp it again. Enables you to maintain a professional flow to your work. I feel awkward when using regular clamps in comparison. They require two hands. You could use a spring clamp to hold it together, then get another clamp to give it a final hold, but the quick grip saves you from having to do that.
Having these clamps in a few different sizes is beneficial as well. Small ones are more frequently used, and don't get in the way. The 33 1/2" is great when you need to hold larger projects together, and you can't effectively use two smaller ones to substitute. Additionally the macro clamps give you deeper jaws for a farther reach, enabling you to use them for securing work, to your radial arm saw table for example. They are fast enough to be used for almost any application. Sometimes I use them to secure work when sanding with a power sander. A couple squeezes and they are on, and one squeeze and they pop off.
After getting the smaller ones, and using them, I immediately order two of the 33 1/2" for larger projects, and for tie downs on equipment, including the drill press, and occasionally the radial arm saw.
Their is a small rubber stopper, which you can readily remove, in order to reverse the end, and make it a spreader as well. Something not needed very often, but difficult to achieve without one of these.
One note is that these have built in rubber pads, that completely cover the metal internal end. That is an advantage when you do not want to mar the wood. That and the fact that you can squeeze these with one hand, creates a mechanism that is easy to use, but not something that you would want to use for strength clamping. As a safety measure, these clamp sufficiently for most operations, but a threaded bar clamp, is stronger. So for those operations where extreme strength is needed, these are not the clamps to use. You sacrifice mountain holding strength for the ease of use. For example if I was using a large bit on the drill press, and drilling into metal, I would clamp it with something more. Even the slightest movement in an operation like that, could cause a snag, sending the piece into movement. If you are using just one of them, at the end of a 24" board, and decide to rout the other end, it will move on you. Securing it with two of them, and it is super tied down. You get my drift.
The big advantage of quick grip clamps, is that they handle wood beautifully, even for glue up operations. Hold workpieces more than securely to do the job in most applications, and are so handy that they deserve more than 5 stars. I would feel lost without them. It is another tool in the must have category.
