2 Vial Spirit Level

A 2-vial spirit level, also known as a double-vial spirit level, is a type of leveling tool that features two vials filled with liquid and air bubbles. These vials are used to determine both level (horizontal) and plumb (vertical) positions on a surface. The two vials are typically positioned at each end of the level to measure these orientations independently. 2-vial spirit levels are commonly used by professionals and DIY enthusiasts for a wide range of applications, including carpentry, construction, tiling, and other tasks where achieving level and plumb positions is essential
