Starrett C604RE-6 Steel Rule

Each rule end is accurately ground to allow reading from either end. Graduations are machine divided (not photo engraved) for uniformity of line width and depth. These rules have graduations on the ends of one face for setting them on edge to use as a height gauge. Both Imperial rules have end graduations in 32nds – the 6″ to 1/2″ and the 12″ to 3/4″. Their edge scales are optimized for easy reading and have 4R graduations with increments in 8ths, 16ths, 32nds and 64ths. The end graduations of the metric rule are in millimetres to 10mm; each face is graduated in millimetres and half-millimetres. They have finely ground edges for accurate marking or scribing.
