Very useful in squaring corners
light weight but solidly built. Different sizes, all quality product.

Easy and reliable
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.

seem sturdy and should work well
I purchased these to compliment a pocket hole jig i bought, while they are a bit smaller than i thought, they look like they will hold up well for their intended use

Nice BUT….
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 6â and 4â had a concave or inward to the center of the X and Y center area. Now as far as ââwas the X and Y plain square?â The answer is yes but I didnât 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 didnât 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, donât try to square a a 2âx3â item with a 4âx6â positioning square… use the smaller one. I will try to update this review with images and measurements on my straight steel edge with 0.001â accuracy over 24â. 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 wonât be disappointed. This was the best deal I could find.

Completely Satisfied
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.

Good for the price
Heck, they only cost me $20. Still, first impressions out of the box are “wow, these are small” and “don’t appear to be as sturdy as the other guys’. I’m positive they’ll do the job I need which is helping square up and hold projects as I’m trying to assemble them.

Pretty accurate and useful
Within a few tenths of a degree of 90 so should work well for hobbyist work. If you’re seeking absolute precision for a more demanding application than typical woodworking then you may wish to look elsewhere.

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

Bons produit

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

I purchased these 90° clamping squares after watching Mark on Start Making (Woodworking). He rated the product highly due to it being accurate (and square). The items are well made and perfect for the job. Thank you!
