3 Vial Spirit Level

Secure Tools supplies a 3-vial spirit level. It is a type of spirit level that features three vials filled with liquid and air bubbles. These vials are used to determine level and plumb positions on a surface. The three vials are typically arranged in a way that allows the level to measure both horizontal (level) and vertical (plumb) orientations simultaneously. 3-vial spirit levels are commonly used by professionals in construction, carpentry, and other trades where accuracy in leveling and alignment is crucial.
