Rectangular aluminium profile with reinforced ribs - high strength and secure grip when working. Extra strong neodymium magnets for attaching to metal building elements: hands-free when aligning and adjusting posts and beams (up to 5 times stronger than standard ferrite magnets). The integrated non-slip stoppers allow for a secure attachment to the marking. STABILA quality bubbles for optimum readability: highly transparent and durable acrylic glass with precision-ground inner contours and fluorescent bubble fluid. STABILA mounting technology ensures long-term accuracy: measuring accuracy in the normal position ± 0.5mm/m and ± 0.75mm/m in the reverse position. Spirit level with two measuring surfaces: precise measurement in all positions. The plastic stoppers protect the profile in case of bumps. Easy to clean thanks to the electrostatic powder coating Equipment: 1 horizontal bubble, 1 vertical bubble, 2 coated measuring surfaces, neodymium magnets. If you are looking for a precise and reliable bubble level with particularly powerful neodymium magnets, this is the right model. The 80 ASM reinforced aluminum rectangular profile and STABILA mounting technology provide precision and long life. The bubbles and measurement surfaces align each other accurately during the production process, and then permanently bond together each other to ensure maximum measurement accuracy over many years.
