140mm/5.5‘’ 90 Degree Positioning Squares Right Angle Clamps Aluminum Alloy Woodworking Carpenter Corner Clamping Square Tool for Picture Frame Box Cabinets

Being as these come in a set of two, I figured I'd need two sets (4 pieces) in order to do 4 corners on a box or cabinet.After setting up my first box, it became obvious that you really need one set of two for each corner, otherwise the when using only one clamp per corner, the opposite side is free to wander, or not line up tightly.This equation makes for a pretty expensive way to get nice 90 degree corners, but in the long run, it's worth it.As someone else said, these work pretty well to hold things in place until you get your large clamps on.I give it 4 stars only because for what these actually are and are made out of, they're awfully pricey.

Amazing product! I originally bought the Kreg Jig 90 degree corner clamp for this job which was broken as I couldn't clamp down the T-joints. I promptly return the clamp to the store and tested another in store which promptly broke after the first use. I searched all over the web for a viable clamp but reviews indicated the clamps didn't have a true 90 degree angle. Eventually, I found these Right Angle Aluminum Alloy clamps and let me tell you these clamps are the next best thing to sliced bread. The clamps are very versatile by allowing you to reposition the clamp anchor along the 90 degree aluminum alloy bar. Additional the clamping mention did not leave any marks behind from where I used the clamps. I know the price seems high compared to other clamps but these are TOTALLY worth it.

Checked every part and the squares for square. Everything was absolutely perfect. The bad news is, unlike all the pictures, they won’t work to hold things together and set glue. The clamps aren’t strong enough to pull stock together.

First impressions of this company: excellent! Alot of companies have no regard whatsoever for how your product arrives. Not these guys, all items carefully packaged and the box filled with bubble wrap to ensure no damage to the product. It really shows that they care about their product and their customers. When buying squares, especially online, the first thing you do is compare them to your own square. They are near perfect. I even took them to work to compare them to a calibrated surface plate. I have zero complaints about the quality of these products or the care the company took to get them to may. Im extremely satisfied in all regards.

I saw these on a favorite YouTube channel. Figured they might help with my cabinet building project. They are simple to use. Well built. I bought two pair and felt a little guilty for spending so much. But if they ensure square corners thats good enough for me.I like that they hold everything square all the way through the glueing process. They are definitely a splurge item for me but I'm glad I made the purchase.

Purchased these squares as right angle clamps for my woodworking shop. They work great and far less expensive than the other red squares and seem to be just as accurate. As an improvement, I would recommend that the clamp portion of the set be a little longer at the "J" curve so that you could inset these deeper into your project. I purchased an additional two sets after I purchased my first two sets, that's how much I liked them.

I really wanted to like these, but the 90 screen screws are not actually at 90 degrees. When I tighten it down the screw pieces either lift from the aluminum block or causes the whole block to twist so it is not flush against the wood. It have used them with just normal clamps, but over all not worth the fuss in the state they are in.

I do love these clamps as accuracy is great but do wish that they didn't slip around while trying to clamp down. They should almost have a price of grip tape to hold them for shifting while clamping

Very well made, good quality. A good addition to my work shop. Like having an extra set of hands.

They are not perfectly square and two of the fasteners will not thread due to poor machining.

Product arrived in perfect condition and as advertised

Great Product I'm ordering another set.
