Level Vial

Level vials are a type of measuring tool commonly used by craftsmen in various industries. They are typically found in the supply class of Measuring Tools, specifically in the Craftsmen's category within the supply group of Measuring Tools.

A level vial is a small, cylindrical glass tube that contains a liquid, usually a colored liquid such as alcohol or oil, with a bubble inside. The vial is mounted on a frame or housing, which is designed to be placed on a surface or object to determine its levelness or alignment.

When the level vial is placed on a surface, the bubble inside the vial will move to indicate whether the surface is level or not. If the bubble is centered between two reference lines on the vial, it means that the surface is level. If the bubble is off-center, it indicates that the surface is not level and adjustments may need to be made.

Level vials are commonly used in construction, carpentry, metalworking, and other trades where precise leveling or alignment is required. They are often incorporated into various tools such as spirit levels, laser levels, and precision measuring instruments.

Overall, level vials are essential tools for craftsmen to ensure accuracy and precision in their work by providing a reliable method for determining the levelness or alignment of surfaces or objects.
