T-square
Architect's horizontal guide
A T-square is a drafting tool shaped like the letter T, with a long blade attached at right angles to a shorter head.
The head hooks over the edge of a drafting table, allowing the blade to slide up and down while remaining perfectly horizontal.
Used for drawing straight lines and as a guide for triangles and other tools: He lined up the T-square and drew a series of parallel lines.
