The Sola AZB3120 aluminum block spirit level is a precision measuring instrument designed for professional applications in construction, carpentry, and installations. This 120 cm long spirit level features three high-precision vials for accurate horizontal, vertical, and 45-degree angle measurements, ensuring reliable results for various alignment tasks. Made from durable, lightweight aluminum alloy, the tool maintains its structural integrity while minimizing user fatigue during extended use. The block design provides stability on flat surfaces, and the clearly marked metric scale with millimeter divisions allows for precise measurements directly on the spirit level. The vials are protected in robust acrylic housings that are resistant to shocks and environmental influences, preserving calibration accuracy over time. With its anodized surface, the spirit level offers corrosion resistance for use under various working conditions. The ergonomic handling profile and non-slip end caps enhance control during use. This measuring instrument meets professional standards for accuracy and durability, making it suitable for tasks such as tiling, framing, plumbing, electrical installations, and general construction alignments where reliable leveling is essential. The product represents the successor model of previous aluminum block spirit levels in the Sola range and incorporates refined manufacturing techniques for consistent performance.
