Corner Clamps for Woodworking, WenCrew 4 Pack 5.5" Aluminum Right Angle Positioning Clamp, Precision Woodworking Tools for Cabinets, Drawers, Frames, and DIY Projects, Durable Corner Clamps

These work really well although the clamps can get a little wobbly. I use 2 of the included clamps and 2 other clamps and these work really well.I use the brackets as squares all the time. The red color contrasts a lot against the wood and is really easy for my old eyes to see.

I purchased these to square up book cases. The 1 X 12 X 8s used for this project were not straight and I didn't have many options to correct that. These right angle clamps helped square up the corners and kept the shelves level. They freed up my hands, simplifying the use of pocket hole screws. The aluminum is high quality with metric and imperial markings. They are easy to place on the project. Tightening the knobs pulls the corners together flush, much the same way pocket hole screws pull two sides together.The clamps are also a handy way to verify 90 degree corners on any project. They work on interior, T type angles, and outside angles equally well. I almost purchased clamps that wouldn't have worked on the T type interior angles and am glad I checked.This is a well made, well designed and well thought out product. It solves a common woodworking problem.

I have wanted a set of these clamping squares for a while but quite honestly the price has kept me from buying. I drummed up the courage and purchased a set to try out.Now, I have a rather robust variety of clamps, bar clamps, pipe clamps, quick grip, clamps, corner clamps, homemade clamps etc….As far as corner joints and butt joints:The original corner clamp was my first go-to. The only draw back is when using the clamp on the bottom or base, it is hard to tighten the t-style screws. It can be used on top as well which does make it easier, but I find myself twisting it around several time to figure which way it goes.My homemade wood square with clamp is simple to use and of course the price is right. The drawback is, the cut has to be perfectly square and being made from wood, it can get damaged. You also have to use another type of clamp to secure a joint. Using a bar or pipe clamp, it does take a little longer to get the perfect joint.I found the metal Clamping Squares to be very easy to use. They are the best and fastest at putting a joint together and adjusting to get the perfect fit. No worries about being square with the solid aluminum frame and no other clamp needed.My overall take on these Clamping Squares is I really like them and is my NEW go-to joint clamp.BUT, I do believe the price is a little high and I would only purchase again if I had a great sale or price reduction.

We were surprised at the quality -- in a good way!The clamps were significantly heavier than I would have thought based on the images and they worked like a charm on the project we had lined up. They were durable enough to hold each corner together for small wooden boxes that we were making with our kids and we haven't had any issues with the corners coming apart.

These were as described and very helpful with the project on which I was working.

Product is made of superior metals, well machined and fits well together, making a superbly tight 90 joint.

Very sturdy and square. Excellent at squaring a droopy cabinet!

Great product !
