Aluminum rectangular profile with reinforcement ribs offers high stability and a secure grip during use. Integrated slip stoppers ensure a firm fit when marking and prevent the level from slipping. The Stabila mounting 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 Stabila quality vials provide optimal readability and are made of highly transparent, durable acrylic glass with precisely ground inner contours and fluorescent vial liquid. The level features two measuring surfaces for precise measurements in all positions. Coated measuring surfaces protect sensitive surfaces, while plastic end caps shield the profile from impacts. The electrostatic powder coating makes cleaning easier. Features include a horizontal bubble, a vertical bubble, and two coated measuring surfaces.
