Extra-stiff aluminum profile with reinforcement ribs for high stability and secure grip during work. The extra-strong system made from rare earths allows adhesion to metallic building elements and keeps hands free when aligning and adjusting posts and beams. Two vertical vials enable quick reading in any position. End caps with slip protection ensure a firm fit of the level during marking. Shock-absorbing end caps made from a two-component material mix protect the profile from impacts. Removable end caps allow for precise positioning and marking even in corners. The electrostatic powder coating makes cleaning easier. The level features two precisely machined measuring surfaces that prevent discoloration of surfaces, such as exposed masonry. The integrated technology from Stabila guarantees long-term precision, with a measurement accuracy in normal position of ± 0.5 mm/m and in folded position of ± 0.75 mm/m. The equipment includes a horizontal bubble, two vertical bubbles, two milled measuring surfaces, and a system made from rare earths.
