Rectangular aluminium profile with reinforcing ribs for high stability and a secure hold during employees' work. Features a particularly strong system of rare earth magnets for adhesion to metal components, enabling hands-free alignment and adjustment of posts and beams (up to five times stronger than standard ferrite magnets). Integrated anti-slip devices ensure a firm hold when marking. Stabila quality spirit levels offer optimum readability with highly transparent, resistant acrylic glass that contains precisely ground internal contours and fluorescent liquid. STABILA installation technology ensures long-term precision, with a measuring accuracy of ± 0.5 mm/m in the normal position and ± 0.75 mm/m in the folded position. The profile enables precise measurements in all positions, while plastic end caps protect it from impacts. It is easy to clean thanks to its electrostatic powder coating and is particularly suitable for measuring tasks in metal and drywall construction.
