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)

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.

I just finished my first project with these 90 degree corner clamps. They are 100% needed for building cabinets. We just don't have enough hands! or a tail... The build quality is high. Solid metal corners that aren't going to bend or even get damaged in a fall. You can crank these down with zero worries! I like the measurements on the corners. I find them helpful for setting up screw holds. Having 4 corners is great, most of the packs I found only had 2 - 90 deg corners so I would have had to buy 2x. This product save me from having to do that.

Use them when making cabinets, work real nice

They are well built and perfectly aligned 90s. They hold well but can slip if you’re not careful with the setup. They are a good design and size for most standard size cabinet builds.

Work really well. A little hard to get use to, but worth the time especially if your only using glue.
