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.

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.

I'm not a typical rater. For 5-stars, do something to exceed expectations. These are aluminum corner clamps. Hard to go above on something like this. 4-stars means good. I do like them. I tried some other plastic ones but these are definitely better than the plastic ones. I finally used them on a drawer I was making. Much better alignment. I wish I had gotten a set before and saved some problems. Good quality with nice, easy screw clamps. I wish they had included a few more screw clamps, but 2 on each does work.

Picked these up to help with woodworking projects and they have been a solid addition to the shop. The aluminum feels sturdy, and the 90 degree corners have been accurate enough for picture frames, small boxes, and cabinet-style assemblies. They hold pieces in place well while the glue sets, which makes it a lot easier to keep everything square without juggling extra hands. I also like the chamfered edges, they have not chewed up my workpieces, and the red finish is easy to spot on a cluttered bench. The storage case is a nice touch for keeping all four together. Just note you will still want your own clamps to apply pressure, these are mainly for alignment. Overall, a pretty good set for the price and very useful for repeatable right-angle setups.

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.

Very solid build and easy to use. Perfectly square and the side measurements are accurate. Dropped one on my concrete slab floor several times and it only got a very minor scuff. Doesn't give to heavy clamping force, which is important for keeping anything square. The clamping bolts also hold very well and show no signs of wear even with very heavy force applied. Biggest thing I would want to improve is the length of the clamping bolts themselves, which will not reach if you are trying to clamp something like 4x4s together. The squares themselves do work with other clamps though so it isnt the biggest problem.

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
