DART professional, robust tape measure with 30% thicker blade which triples the durability. The magnetic ended hook makes it easy to use when working with metal and enables the user to take measurments single handed. The rubber casing reduces breakage on impact and the matt finish of the tape makes it easier to read measurments. It features strong and positive recoil action. The II Accuracy Mark (Roman Numeral 2) gives any site foreman confidence of the accuracy when using the tapes on site.
