How the Pros Use It
Add a third leg off a 90° corner—the square holds parts perpendicular, even outside your setup.
Move the square inside the setup to hold parts along the edge—no need to stay locked to the corner.
The thin foot design allows alignment in tight gaps, squaring the outside with materials in close proximity.
