Preciva90 Degree Mini Positioning Squares 2 Sets (2.32''x 2.32''), Aluminum Alloy Right Angle Clamps Fixing Clamp, Carpenter Corner Clamping Square Tool for Picture Frame Box Cabinets Drawers (Red)

Sturdy chunks of metal and yet they were packaged better than most electronics i have received. Impressive.They are dead on square. Compare perfectly to the larger woodpeckers clamps i have.The very nature of this clamp type is fiddly. No matter what brand or size. Cannot deduct any stars for that.Would definitely buy again. I ordered both the red and black anodized, no differences in them, simply different colors. ( it was an amazon shipping issue that caused me to ordered both colors)EXCELLENT product.

Before this, I always struggle to clamp the last corner in a box, and make it perfectly square. I just use strapping tape while all pieces of the box are against a straight edge--then glue and roll it up 45º to 45º. That works well, except on the last corner. With these/even one clamp I can make perfectly square boxes.

I've been successfully using these brackets and clamps to make accurate right angle joints in multiple projects. It took a little bit of practice to get the the clamps positioned and secured, but the results are well worth the little bit of practice I needed. Both right angle clamp bodies are accurately machined and the clamp rods and braces are easy to assemble and position. They hold my work pieces accurately at 90 degrees and allow me to secure the joint with glue or fasteners. I've made so many projects over the years with angles looking like they were 90 degrees, but I could never make a square without a gap when putting the last to edges together. Now I can get it done with ease and I'm much more relaxed knowing I've got confirmation that my angles are good.

In my experience this isn't gonna get you a laser-perfect 90 degree angle, but it will get you something very square much more easily than doing it without a tool. Pretty easy to use, slight awkwardness getting everything in place but once you've got the clamp around the materials and you start tightening it holds well. I've already had two occasions to use them and they did their job, no complaints here!

The product is well made. It's almost like a work of art. The problem is that you need to get the frame together quick before the glue starts to dry and there's just too much fiddling around. I also couldn't really get a nice seated joint with these.

Very well made. A nice addiction to my clamp collection. Perfect for small frames and boxes.

Well designed, excellent workmanship

Exactly what I needed

The media could not be loaded.  This set worked perfectly to help me glue two odd shaped pieces of wood at right angle.What I liked:1. It was well presented, I was impressed with the packaging.2. All the squares were perfectly squared, I measured twice with two different rafter squares just to make sure.3. It survived two accidental drops and still stayed perfectly squared. I believe it's small size helped it to survive the drop since my larger squares from another set was bent slightly after dropping from table height.What I don't like:1. There were very minor imperfections in the paint job and the molding of the knobs. However these are just anesthetics and do not affect the performance of this product whatsoever.Overall I am very happy with this product and would definitely recommend to others.

The media could not be loaded.  First thing I did with these was to check these against my own square which is calibrated and these are spot on. The set includes kit to set up two corners simultaneously. My only gripe is it would have been nice to have a set to do all four. If you're going to be securing 2ith screws only, two is fine, but if you're doing glue-ups, you want four, which means buying two sets. Beyond that, they are clamping squares, which all work the same. These are smooth and the aluminum pieces feel like quality and they look really nice with the red finish too.

Good value for price. The foam block is nice, would have been better to come in a plastic case. Overall sturdy and easy to use. Will work for what I need it for
