Aristo Adjustable Set Square 10
Perfect for designers and architects, this adjustable set square is made of clear 3.5mm thick Plexiglass and is great for drawing and measuring angles. It consists of a large set square with a hypotenuse (longest side) measuring 25cm. The hypotenuse is mounted on a bolt and an arc scale, so that it can be swung out from the rest of the set square; this allows the set square to function as a protractor.
The hypotenuse can be fixed in any position on the arc scale or left unfastened so that different angles can be measured. The arc scale runs from 0 to 45 degrees and 90 to 45 degrees. It bears 1 degree and 1/2 degree increments.SKU: 21001090:21001090
