Aluminum rectangular profile with reinforcing ribs offers high stability and a secure grip during use. Integrated slip stoppers ensure a firm fit when marking, preventing the spirit level from slipping. STABILA installation technology guarantees long-term precision, with measuring accuracy in normal position of ± 0.5 mm/m and in folding position of ± 0.75 mm/m. Quality vials provide optimum readability, featuring highly transparent, resistant acrylic glass with precisely ground inner contours and fluorescent vial liquid. The spirit level includes two measuring surfaces for precise measuring in all positions. Coated measuring surfaces protect sensitive areas, while plastic end caps safeguard the profile from impacts. The electrostatic powder coating makes it easy to clean. This product is particularly suitable for gardening and landscaping, reinforced concrete construction, carpentry work, and tiling tasks.
