A pipe laser is a specialized tool used in construction and civil engineering to provide accurate alignment and grading for pipe installations. It projects a visible laser beam along the interior of a pipe or trench, helping to ensure proper alignment and slope. Commonly used for drainage systems, sewage pipelines, and other underground utilities, pipe lasers are designed to be durable, water-resistant, and easy to set up. Many models include features like remote controls, adjustable grades, and long battery life to improve efficiency and accuracy on the job site.
