Extremely durable, torsion-resistant aluminum R-profile. Extra-wide measuring surface for exceptional stability, preventing tipping during the measurement process. Three guiding edges ensure precise marking along the entire profile length. A continuous handrail with a finger groove provides excellent grip during measuring and transport. Coated measuring surfaces protect delicate surfaces. A continuous rib over the horizontal level further stabilizes the profile. End caps with slip stoppers ensure a secure 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 placement and marking even in corners. The R-profile shape enables easy removal of building materials. Easy to clean. STABILA installation technology ensures long-term precision and measurement accuracy in both normal and inverted positions of 0.5 mm. Features: horizontal level, vertical levels, coated measuring surfaces.
