9001 Can-Do Clamp Corner Clamp

These are great and heavy duty metal. They are much sturdier than the "plastic" items that are "spring loaded". You can even hold two pieces together than are different thicknesses. I had no problem with holding 2x6's together and they should be exceptional at building picture frames during their build. I bought two so I can hold both the tops and bottoms of larger panels together during assembly.

I purchased four of these Can-Do Clamps for assembling Bee Colony Boxes. The maximum thickness of pass-through stock on these is 1 and 3/4 inches. The maximum lay flat miter or T-Joint thickness is 2 and 3/4 inches. The Clamp body is nice and heavy, painted aluminum. The threads are of good quality and the clamp holds very firm with very good gripping of the stock. The corners are OPEN, so any glue can drip down the joint without messing up the clamp, you also have open access to the joints for screwing or drilling the corners without the clamp getting in the way. You can bench mount it, wall mount it, or use it to shim stock while locking down the 90 degree angle. I use two at a time, as shown in the video, and have them clamp opposite 90 degree angles, this makes all angles a true 90 degrees. They work exactly as I expected them to, I expect these clamps to last a VERY long time as there really just isn't anything to wear out. I recommend them without hesitation or reservation. When it comes to the inconvenience of the sliding T-handle for adjusting, I just get it well within a few centimeters of the stock I plan to clamp, then just put it on and finish tightening.

This thing seems super sturdy and it works fairly well. If you're going to use it for things like cabinets (big panels of plywood) i would suggest using two right angle clamps at a time, one at the top and bottom. It can be slightly annoying to use with the large handle. If it's sitting in the middle of a table, you can only do 180 degrees at time, then adjust the handle to do the next rotation. Place it on the edge of a table if possible, or make sure to get it pretty tight before installing so you only have to do a couple rotations to tighten. Some people might prefer the large handle because you can seriously tighten it down if you want, but for my purposes, a more ergonomic handle like they have on the horusdy 90 degree clamp works far better. Also, note that the tightening happens on the inside corner (the horusdy clamp tightens on the outside corner). I find I prefer working with an outside corner clamp for my purposes (cabinet building), but I think both are equally useful.

These clamps are amazing compared to the old corner clamps I had been using for years in my woodworking hobby. The old clamps were hard to align and I was never guaranteed a 90 degree fit. These clamps are not only great from an ease of use and accuracy perspective, but they will hold up versus the resin/plastic comparable products that I read everyone is breaking when they clamp them down. The price is definitely a little higher than what I wanted to spend per clamp (I bought 2). After using them I will now invest in more and hoping I will never have to buy another set. I did read the complains about the red paint transfer and while I did see some of that it was minimal, and I was able to sand it right off. I'm glad I bought these versus the plastic versions which are cheaper. The other nice thing about these is that you can join two different thicknesses with no issues. Overall I am very satisfied and definitely recommend these to anyone needing good corner clamps for woodworking.

It's good. It's sturdy. I like the open area at the joint. First time I used it was to square up metal framing for welding. Worked well. Couldn't have welded the frames with some of the jigs out there because of a lack of clearance at the joint. It does take a little effort to get your pieces to mate correctly, as it tends to want to pull them apart as you tighten it. Overall, still rates 5 stars for a home handyman like me. Not sure I'd use it in a production facility but I don't have one of those, so all is good.

Wish I had these years ago. It is funny how some things are used so often after you purchase them. These little clamps are well built for price you pay. If you want to do metal work, they might work for very light occasional use...but I would go with larger clamps. I needed a clamp to speed up my wood target making process. The first target took 5 times longer to build, but by the 10 target I was really moving. You need two clamps for the jobs I have used the clamps for. I image will end up purchasing 4 clamps to speed up the production process. The Clamps are easy to store, light, and well built. Great item.

These clamps are amazing. I originally thought they were much smaller based on a similar clamp my father-in-law has, but these are much heftier. When they arrived I actually thought they would be too big for the initial project I bought them for, but I still managed to use them because the clamp surface has a nifty swivel design, allowing me to swivel just enough for it to fit the corners I needed to clamp. I was unaware that the clamps swiveled in such a fashion to allow for additional applications. I thought they merely clamped down on the corner of a 90 deg. angle with matching sizes, but they can do much more than that. Since they swivel, you can easily use them to join two different thicknesses of wood. These are way more versatile and robust than I originally thought and well worth the cost. I'll buy two more when I can afford them to clamp glue custom made frames without having to wait and switch out two corners after drying. Well worth the cost based on the versatility they provide, and quality. Clamping is smooth and very strong.
