The T+ Square is Divide & Rule's take on the classic T square, used for drafting since technical drawings first existed.
The Divide & Rule T+ Square is scaled down to suit A4 pages with a 210mm long rule piece. The T+ Square allows for greater flexibility than just a 90° square as it allows for 15° increments from 15° to 175° around the protractor section. The rule section can be quickly removed and located to the different angles on two brass pins. Whichever angle the rule is set to the zero point on the rule lands at the centre of the protractor.
The T+ Square can be used on either the left or right side of the page as the rule has two sets of dimensions orientated to suit. The protractor section is the same size as the Protractor 180° and so has the same 180°/180mm outer edge and can be used with either the Rule 150mm or Rule 300mm. It also has millimetre markings to the flat edge to easily allow for creating parallel lines across the page.
All the markings for degrees and millimetres are incremental to ease reading and the back edges of the rule has a bevel to minimise ink smudging.
