Review on 🪚 Woodworking Carpenter Clamping Tools for Workholding – Aluminium Power & Hand Tools for Industrial Positioning by Mike Davis

I have them. and having read reviews that they are not square. all four checked. Three of them go perfectly with my Red Bird square. (guaranteed to be square within +/- 0.008 over 7 inches) and one of them showed a bit of "daylight" near the top. Well within what is required for woodworking. If you need more precision, spend big and get Starrett tools. Buy some inexpensive 4" Irwin clamps to use with this. They hold the square of my current project very well.
