The SUPER SQUARE® is an extremely handy sliding ruler-rafter-angle-layout-tradesman's tool made in the USA by Quickway Tool Co. Designed to last, it is made out of anodized 6063 T5 aluminum with a stainless steel knurled thumb screw.
Some of its many advantages over standard triangle squares of the same size are:
- A longer marking edge, the ability to scribe parallel lines up to 12"
- Able to check interior "and exterior" corners for square
- Helpful for framing layout with its 1 1/2" to 5 1/2" inside ruler
- Makes a good straight edge for cutting with your favorite power saw
The SUPER SQUARE® is many different tools in one that saves time and money.
