If you like using your Perfect Adjustable Square, but found it was only adjustable to 1/2in increments on the outside and whole numbers on the inside, the here’s the good news! There is now an adapter to change the outside measurements to whole numbers.

The new adapter makes the interior square adjustable from 5-1/2in up to 21-1/2in and the exterior square adjustable from 11in up to 26in. The adapter is a slightly different colour so that it stands out from your other pieces.
