Laser levels are precision tools used in construction, surveying, and industrial alignment applications. They project a visible laser beam to establish straight lines or level planes, ensuring accuracy in tasks like grading, framing, and machinery installation. Common types include rotary lasers for 360-degree leveling, line lasers for cross-line projections, and dot lasers for point alignment. Many models feature self-leveling capabilities, high visibility, and rugged designs for outdoor use. Industrial-grade laser levels often integrate with mounting systems and offer enhanced durability for demanding environments.
