A spirit level is stressed on the construction and it can easily happen that it falls down. It is therefore all the more important that it continues to measure as accurately as it was on the first day, even in the event of daily stress. The two vertical bubble levels allow you to read the data in any position. The stable reinforced aluminum square profile and the mounting technology of Stabila with firmly cast in spirit level make the device the perfect partner for hard construction site applications. Stabila spirit levels: Precision that will last a lifetime.This text is machine translated.
