This compact model features a die-cast aluminum profile with a beveled shape, making it one of the most robust levels from Stabila. With this model, you always have your hands free when aligning and adjusting components on metallic surfaces. The 81 SM Torpedo is equipped with a rare earth system that ensures optimal adhesion. The level and the machined measuring surface are precisely coordinated during the production process and then permanently bonded together. This way, Stabila ensures that the level continues to measure with absolute precision even after many years.
