90 Degree Corner Clamp for Woodworking, Positioning Squares Right Angle Clamps 5.5" x 5.5" Aluminum Alloy Corner Clamping Carpenter Tool for Picture Frame Box Cabinets Drawers (Red)

The product itself (woodworking corner clamps) is well made and works well. I find it a very useful tool.I would have given it 5 stars, except for the poor product quality control: One of the included L-bolts turned out to be defective and was unusable. (See uploaded photo.)I initially didn't notice the defect when I opened the box soon after I received the product. By the time I tried to use it in a project, it was almost - but not quite - too late for a return. I contacted Amazon and they shipped out another one in exchange for my shipping back the original - only a minor hassle.This may go without saying, but given my experience I recommend that you check yours very carefully for a similar issue as soon as yours arrive; it could be too late for a return if you waited until you need to use it.4 stars.

I haven't had the opportunity to use these yet but they appear to be well-built out of anodized aluminum with laser etched markings. I did check the markings and they appear to be accurate, at least to my well used measuring tape! I'll be using these soon to build some workshop cabinetry. I knocked one start of because like all of these types of tools...I wish there was a case that this clamp set came with as your kind of left wondering how to store all of the pieces, I suppose you could glue the packing materials to a piece of ply or even cardboard and just use the setup as a shadow foam organizer that can be placed into a drawer.

REVIEW: 90 Degree Corner Clamp for Woodworking, Positioning Squares Right Angle Clamps 5.5" x 5.5" Aluminum Alloy Corner Clamping Carpenter Tool for Picture Frame Box Cabinets Drawers (Red)I really like that the clamps have measurements on them, in both inches and millimeters. It makes it so much easier to use that scale than to use a measuring tape or other tool with a ruler etched in. The numbers on the edges are laser engraved and an off white color. This makes them so much easier to read. The clamps are also 5.5 inches long on each side side. This is certainly long enough to keep a straight 90° angle.The orange color on these right angle clamps is wonderfully painted and gives them a nice looking finish.This set of Chaoos 90° clamps, sold by FOUUAAOOU, are not just another set of cheap 90° clamps. They are made of an Aluminum Alloy and the screws are made of Stainless Steel. These are both heavy duty and well made to last a lifetime.The angle is exactly 90° and will produce perfect 90° angles on any woodwork project you have going.Compared to major brand clamps, that are likely made the same as these, this set comes in with a much lower price, and they do the same job. I highly recommend them !The only issue I have with this set, is that the numbers are only etched on the edge of the clamps. Many clamps, similar to these, have the numbers etched on both the edge of the clamp and on the face, making it easy to see no matter what angle they are being looked at.

These clamping squares are handy little gadgets when making boxes or anything with right angles. I had a similar set of two already, but since boxes have four corners I wanted another set. At first glance I thought these were identical to what I had already as both are import clones of other brands, but there are some differences.My older set came from another source and is generally "beefier". The main dimensions are the same - the length of the legs and thickness. But the width of the legs on this on is less by about 4mm tho the hold size is the same. Also the clamp bolts are the same, but the clamps themselves are overall smaller. This is the only thing that I feel makes them a little less useful as I find the larger clamps a bit easier to get positioned, but if you're working on smaller items this might be good.I do like these knobs a bit better, these being more rounded and six point, with the others being only three. I find these to be more comfortable.All that said, I doubt there is any real difference in day-to-day performance. For the type of jobs you use these things for, these are plenty strong enough and then some. This also means they're lighter so that may be an advantage.As for accuracy, which is probably the most important metric, I checked these against my machinist square and they're spot-on. You're likely to have more problems due to slightly warped wood than from these.Overall, I'm happy with these. Personally I'd like the clamps to be a bit larger like my older set, but this is still a nice set and I'm sure I'll be using them just as much as.

This FOUUAAOOU 90 Degree Corner Clamp for Woodworking are made of aluminum and feel sturdy. The are undersized for larger boards/projects. I used them to join a couple 2X4s for a cornhole board I'm working on. They do the job but a larger clamp would have provided more stability. These clamps are better suited for smaller stuff such as a small drawer, picture frame, etc.The no frills packaging was fine by me. However, no instructions are included so you might need to experiment a little bit if you've never used corner clamps.

I have purchased several of these sets from Amazon over the last year, as I’m improving my at-home woodworking setup. This style of clamp is great for making boxes, which is the basis for most woodworking projects. To be efficient, you’ll need several sets of these, but all of the different versions I’ve purchased have worked the same. These are no exception. They are square and will hold two pieces at a right angle while you attach fasteners. They do not come with instructions, but if you watch any YouTube videos about woodworking you are bound to see these being used.
