90 Degree Positioning Squares, Clamping Square, Right Angle Clamp Corner Clamp Woodworking Tools for Wood Cabinets, Carpenter Tool for Photo Frames Box Drawer, Set of 12（3" 4" 6")

light weight but solidly built. Different sizes, all quality product.

This is my third style of corner clamps. I think they are great, especially for the price. Each different style has their own purposes and these are very helpful. The different sizes have a wide range of applications.

These 90° corner clamping squares are not as big as I thought, but overall worked great

Makes for easy clamp up

I am very glad that I got these and the first thing I did was to check them with my machinist squares Starretts at 0.001 accuracy. Now here is the thing, looking at this as a X and Y position (left to right and front to back) the X and Y solid measuring sides on the 6” and 4” had a concave or inward to the center of the X and Y center area. Now as far as “”was the X and Y plain square?” The answer is yes but I didn’t see some of the perfect surface joining as others showed in their photos and to be honest, as a professional photographer this is not easy to Photograph because we are talking about hundreds of an inch in not perfectly square. Remember, this is plastic. It is solid feeling and almost difficult to bend (I didn’t want to break mine) so for 98% of the needs out there it will be fine. Wood workers will love it. But for me I either use the whole length of the measuring sides on nothing at all. In other words, don’t try to square a a 2”x3” item with a 4”x6” positioning square... use the smaller one. I will try to update this review with images and measurements on my straight steel edge with 0.001” accuracy over 24”. I think these are great and I would not hesitate to buy them again. My metal squares are the best but not as clamp friendly as these are. Buy them, you won’t be disappointed. This was the best deal I could find.

My wife wants a couple cabinets made and these will be perfect to use. I'm sure to get square corners with these. They will make the job so much better and easier. I should get a lot of use out of them and they should last for quite a few years.

Narrow and flimsy. Ok for small glue ups.

Used these to make a 4' frame for an artist canvas. The cross bracing is dadoed. Everything else is a combination of wood glue and pocket screws. I added gussets in the corners later. The positioning squares did exactly what they were designed to do until the glue dried. Frame came out perfectly square. Keep in mind though, these are not machinist squares so don't rely on them for setting up your tools to make precision cuts. For assembly work they're more than sufficient and I can recommend them.

Not precisely square but pretty close. A piece of blue tape on the larger ones & i have a perfect 90 degrees.

Bons produit

They are nice addition to my tools for making, gluing and fabricating frames

These corner clamps are very solid, manufactured from rigid plastic. They seem accurate and as a 12 piece pack are great value

Stabil und gut
