Corner Clamp for Woodworking, 90 Degree Corner Clamp, 4 Pack 5.5"x 5.5" Aluminum Alloy Right Angle Woodworking Tools, Positioning Squares for Picture Frame, Box, Cabinets, Drawers

I am really impressed with the excellent quality and usefulness of these corner clamps. Just taking them out of the box I felt I had purchased a very substantial and precise item! They work exactly as expected and are a pleasure to use. Worth every penny!

Excellent value for the quality. These aluminum corner clamps are very rigid and maintain a true 90-degree angle, which is critical during cabinet glue-ups. I’ve used hard plastic clamps in the past, and these provide significantly better stability and accuracy. The white, high-contrast measurement markings are easy to read and useful for alignment. Machining and tolerances appear precise. I would confidently purchase these again.

These corner clamps are a great tool to have in my shop. They are dead square. They are great for set up and glue ups of 90 degree joints. Being that they have measurment scales, then can also be used to set up blade and bit height. They can be used inside or outside of the joints. They are made from solid aluminum and are very durable. The included clamps work well but you can also use most other clamps that you are comfortable with. The included case makes it easy to keep all the parts together as well as protecting the squares. You will find many uses for these clamps after you start using them. They are a fraction of the price of the other red clamps making them a bargain.

The DIYLOG 90 degree corner clamp is solidly built and feels like good quality right out of the box. It holds pieces square and secure, and it did exactly what it was advertised to do. I used it for basic woodworking projects and it performed reliably without slipping or flexing. The only reason I’m giving it four stars instead of five is that it can take a little adjusting to get everything lined up just right, but once set, it works well. Overall, a dependable clamp and a good value for the price.

This set is very nice. Good sturdy carrying case, comes with 4 squares (and they are true 90!), 8 L-bolts, 8 clamping blocks and 8 matching locking nuts with washers. These are very easy to put up and mount to a cabinet carcass. I would not use these as clamps to hold the cabinet together while the glue dries (still use proper compression clamps), but in terms of holding right angle alignment, these are really good. See pictures. FYI, this is a 1/2" thick workpiece in my photos and the nut is just about at the limit, so you may need to use some spacer blocks for thinner sheets of ply. And if you need to clamp some really thick stock, the bolts are +/- 4.25" long on the thread, minus an inch for the aluminum clamping block, so I could see clamping a 3" thick table leg with this no problem. The most important thing about these is: they are square, unlike my cheap Clamp-It brackets, which were apparently AWOL when their manufacturer was handing out 90 degree prizes... None of mine are square and what's even worse, each one is off by a different amount. That's why I bought these aluminum ones instead. Happy days from now on.

Wow! I’m really happy with these. Some have criticized the fact you have to assemble the clamps, but other than that I don’t see any issues with this design. It’s compact and functional. The clamps are easy to adjust and are versatile for large and small projects. The pieces appear to be very square and accurate.

A very simple product but really well made and thought out… and pretty! Admittedly pretty doesn’t matter for something so utilitarian as corner clamps but dang if the bright red metal isn’t pleasing to look at while on the job. Came with a very cute carrying case too. Easy to use, sturdy, and allow you to do some more unusual 90 degree joins than more conventional clamps will. Would buy again.

Great set of square corner-clamps! Easy to use, solid, light, accurate and convenient. I made a guitar display case for my granddaughter. (She won an autographed guitar used at a TSO concert). The mitered corners needed dowels for strength and it has a fitted door, so the corners had to be a dead accurate 90 degrees. These clamps easily held the box square during glue-up and drilling. This tool made it so much easier to keep this large box square throughout its construction. I use them on smaller box making as well.

Un producto muy útil y de buena calidad. Práctico.

seem ok have not tried them in action yet

Well made and accurate. These clamps are ideal for Woodworkers looking to take things to the next level. Simple to use with a useful storage case.

Perfectly square. Solid. Looks as good as they seem in the pics. Good purchase.

Can see these getting a lot of use
