T-square

A T-square is a technical drawing instrument used by draftsmen as a guide for drawing horizontal lines on a drafting table. It may guide a set square to draw vertical or diagonal lines, its name comes from its resemblance to the letter T. T-squares come in varying sizes, common lengths being 18 inches, 24 inches, 30 inches, 36 inches and 42 inches. T-squares are used to measure and cut drywall. Drywall T-squares are made of aluminium and have a 48-inch long tongue. Higher-end table saws are equipped with T-square fences; these table saw fences are attached to a rail only on the front side of the table unlike traditional fences which clamp to both the front and the rear of the table. A T-square has two components—the long shaft called the "blade" and the short shaft called the "stock" or "head"; the T-square has a transparent edge made of plastic which should be free of nicks and cracks in order to provide smooth, straight lines.
