With normal measurements on the top of the blade, the reverse blade markings take into account the tape case dimensions, so when you measure internal spaces you simply butt the case up to the end and read the measurement. Clever stuff! An ultra strong blade coming in at 25mm wide gives great strength and durability in the horizontal plane – with a stand out of 2.2m approx. Dual Markings are clear and precise giving accurate, easy measuring.
