90 Degree Clamp, Cabinet Clamp, 5.5" x 5.5"(14 x 14cm) Aluminum Alloy Right Angle square Tool, Corner Clamps for Woodworking Tools, Right Angle Clamp, Drawers, Picture Frame (4pack)

I’m a little confused as to why these shipped with a pair of tiny white gloves but the clamps seem like they will accomplish exactly what I need them to do.

Love these. They work really well and come in handy often.

After about 15 projects I used these for here are my thought:This setup is a little slow and clunky. They can only be used within a 1/2” of the edge of the work piece otherwise the pin wants to slip. I also tend to need to make minor adjustments back and forth to get a close joint. This takes away some valuable time during a glue up, so I find it better suited to for nail or screw joints, or only glueing 1 or 2 joints at a time.On a positive note, they are well made and square.It’s helpful to put a little thin rubber or foam on the T block to avoid damaging the surface of your work piece.Also, no clue why it comes with white gloves.

These corner clamps are excellent. They are accurate, easy to use, and are very versatile. The quality is also top-notch. I was very impressed by the fit and finish of these when I first opened them up, these are S-tier quality.The clamps that come with these are great, but you can also use other f-style clamps with them if you need to use more than one clamp per side.These became a go-to tool in my toolbox after the first use. The 5.5" length is perfect for a lot of my work. And after enough experience with these, you'll find some clever "hacks" that will make these indispensable in your workflow. For example, if you clamp two of them together into a "C" shape, you now have a tool for making perfectly parallel marks on work pieces or holding on work piece parallel to a second one. This is a hack a use a lot for spacing shelves, since it's easier than finding a scrap board to cut down to size.I would recommend getting 8 of them if you plan on using these to build boxes. You really can't have too many of these in your shop.

Sturdy. Well made. Should last a lifetime+The video is silly with the clamp on the outside. The second clamp is redundant and will likely get on the way.

Good weight, not cheap feeling perfect size and most of all sturdy and square.

I checked these against an expensive engineers square and the were dead on 90 degrees and pretty inexpensive compared to others. I use them a lot in woodworking.

These are great clamps, but as with all things, you get what you pay for. Based on my digital angle finder, the accuracy of these clamps (inside and out) are about +/- 0.1°. The error equates to about 1/32" over 18". That can certainly become significant over longer lengths, but so far I haven't found it to be a big issue. Other sources of error like material cut accuracy, movement in materials, work surface accuracy, etc seem to offset this one way or the other. Also, as others have said, holes in the angles are a little too big for the posts. They could be smaller, but with a little patience and care, they can still be installed without too much fuss. Do these two details warrant a poor review? Certainly not! If extreme precision is an absolute must, then the high end red brand can be purchased for about 200 bucks more than these. Again, you get what you pay for, and these are well worth the price. I might break down and spend the 250 bucks for the good set of four someday, but until that time, I'm quite happy with these.
