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 bought this as a gift for my husband for Father's Day. He absolutely loved it! He has already used it multiple times. The item is as it appears in the description and the fact that it's metal is a huge deal for my husband. It's easy to use and understand how it works. The clamping and weight give a sturdiness that I wasn't expecting. Size is perfect and compact with the storage container! Definitely a must buy!

As someone who is new to carpentry and is trying to start his own career in the industry. I feel these corner clamps are a must have they are so easy to use. They store quick and easy in the perfect small case they come in. Easy to understand easy to use. 5/5 stars would recommend. A light weight they grip and stay in place. An the adjustability makes it nice for big or small boards

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.

The positioning angles are very accurate and well made. I like the scale markings that are provided on all exposed surfaces. The knobs and fixing blocks are perfect while the extension bolts could use some improvement. The threads on the bolts are very sharp and cause the fixing blocks to "hang-up" and difficult to remove. I would suggest the threads be rolled after cutting. The hook end of the bolts could be a little longer, maybe 1/2".

I got this Clamp set for working with aluminum extrusions building 3D printer frames and tables and carts and such. It really clamps the work securely. It is light weight and the case to store it in is pretty nice. I don't notice any weak points or anything. I think it will be durable.

Very good quality ,exactly like on the photos,very useful tool for making cabinets,and even drilling wholes. I am really happy from the purchase.

I purchased this Corner Clamp Kit back in September 2025 because it looked like it was well made and came with the mounting hardware to accurately set up 90-degree corners. I have been very pleased with the purchase and highly recommend this kit for anyone wanting complete accuracy when setup is crucial. I built this little table using some 1 x 2 stock and 3/4-inch Birch Plywood, used a dark stain, and then coated with polyurethane for a durable finish. The clamps are adjustable and really hold the material tight. You can't go wrong making this purchase greatly enhance your ability to making a square and stable project. DIY'er Ernie.

Great system--have also a Woodpeckers set--cant see a difference between the two--this comes in a nice case--angles are true--clamps solidly--grips on both inside and outside corners--takes a little time to spin the knobs down to 3/4" size, so end up leaving them assembled--so speed to assemble clamps a little longer then I excepted but acceptable--light weight--fit a variety of corners--I like them

Un producto muy útil y de buena calidad. Práctico.

seem ok have not tried them in action yet

I am not a wood worker but I had to build some wooden frames for a home project. These things helped me immensely and they turned out great

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

Can see these getting a lot of use
