Great to have in the workshop. These are great little corner clips/positioning squares and I am very happy with them. My son carves a lot of wood, so I know he'll make good use of them, but I had to glue a part of the frame that separated from the other three parts (think of a picture frame that has one side removed). These mounting brackets made repairs very easy. I used this square with small clips to hold it in place - one inside, one outside. This worked really well and held the frame together until the glue dried and I was also able to hammer in two thin invisible nails for extra security. Great positioning squares to add to your bracket arsenal. They say it's never too much.
