The quick-stabilising 400g steel bob on the Plumb-Auto provides an accurate plumb line within seconds. By using either the magnetic panel or the retractable pin, it can be secured to steel, timber or plaster surfaces before dispensing a line to the required length.The Plumb-Auto is ideal for all building and decorating applications, and the magnetic feature is an asset when working on steel fabrications where nails and pins are ineffective.
