- Class II accuracy, with stud and joist markings every 16 in and 19.2 in.
- The Tru-Zero hook slides to allow for its own thickness; a special slot lets a nail act as a pivot for drawing circles and arcs.
- Its shock-resistant rubberised housing offers protection against drops and impact damage. It has a removable belt clip, a fabric wrist loop, and a thicker blade for longer standout.
- A heavy-duty spring and blade system is designed for durability and long service life. The tape conforms to European Measuring Instruments Directive (MID) specifications.
