C.H. Hanson's a-SQUARE folding squares provide the accuracy and handiness of conventional utility and framing squares, but can be folded to the profile of a yardstick for convenient storage. a-SQUARE models feature a patented precision-locking mechanism that locks the square securely in place to guarantee precise right angles. Available in a range of sizes from 12" x 12" to 48" x 48".
