Extra-rigid aluminum profile with reinforcement ribs for high stability and secure grip during work. The extra-strong system of rare earth magnets allows for attachment to metallic construction elements, providing free hands for aligning and adjusting posts and beams. It features shock-absorbing, removable end caps that ensure precise positioning and marking even in corners. The level includes two precisely machined measuring surfaces that prevent discoloration on surfaces like exposed masonry. The STABILA installation technology 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 design includes a horizontal bubble and two vertical bubbles for quick reading in any position. The end caps are equipped with anti-slip stops to ensure a secure fit of the level during layout. The electrostatic powder coating makes cleaning easier.
