Sirius Tuff Jack tape measures are designed to provide maximum protection against drops and impacts; they are encased in a shock-resistant outer layer which also provides extra grip. Additionally, unlike the Contractor and Pro 2 ranges, these tape measures have magnetised hooks, enabling direct attachment to metal surfaces. They have thick, wide and durable nylon wrap blades designed for longer standout.
