Description The STABILA Type 81S is a strong lightweight spirit level featuring a cast aluminium alloy profile in an especially slim form. Extremely sturdy with electrostatic powder coating for scratch resistance and easy cleaning. The special shape of the profile makes it ideal for many craftsman, and the 25cm/10″ length is a particular favourite of scaffolders and steel erectors. This spirit level can be used in the overhead position by turning the level upside down. In this ‘transfer position’ you can then precisely measure from underneath. Features one horizontal and one vertical vial, vials accurate to 0.5mm per metre (0.029° = 0.5mm/m) in normal working position and 0.75mm per metre (0.043° = 0.75 mm/m) in overhead position, and a milled measuring surface. Vials are guaranteed to remain accurate for 10 years.
