Aluminium profile spirit level


Extremely torsion-resistant 4-chamber profile (60 x 26 mm cross-cut). Highest accuracy (0.5 mm / m) due to ultrasonically-welded vials. Inverted measurement (0.5 mm / m). The domed round vial with magnifying effect provides unsurpassed readability, also for inverted measurement. Two milled measuring surfaces (up to 200 cm) Shock-absorbing rubber end-caps preserve high measuring accuracy.

Also available as a magnet variant.
