This light and versatile level is an invaluable part of any tool box. The compact design and magnetic base makes the 70 TMW an ideal tool for levelling steel surfaces and working in confined spaces. A useful feature is the rotatable angle vial for reading and defining gradients. It fits into a side pocket of any trade trousers, so it can be with you at all times. As with all STABILA levels the vial is precisely aligned with the measuring surface then locked together ensuring long life accuracy.
