STABILA is celebrating its 135-year anniversary with more special models of its tried-and-tested spirit levels sets of types 80 AS-2 in an exceptional Dark Shadow design. 80 AS Dark Shadow spirit level set consists of two special models in lengths 60 cm and 120 cm. The 80 AS-2 Dark Shadow set with an additional second vertical vial is available in lengths 60 cm and 120 cm. The aluminium rectangular profile features reinforcing ribs for high stability and a secure grip when in use in the field. The anti-slip stoppers integrated into the impact-resistant plastic end caps ensure a firm hold when marking and prevent the spirit level from slipping. The spirit levels have two measuring surfaces each, enabling accurate measurement in any position – including the reverse position. Measuring accuracy is ± 0.5 mm/m in the normal position and ± 0.75 mm/m in the reverse position. Both measuring surfaces are coated to protect sensitive surfaces. The electrostatic powder coating makes these tools easy to clean, helping to remove the kind of dirt that is typically accumulated on construction sites.
