Bosch GLL 12-22 Professional

The Bosch GLL 12-22 Laser provides reliable horizontal and vertical leveling for interior finishing tasks.

Built for the Job

This leveling tool serves as a primary reference for interior trades. It projects highly visible red lines that cross at 90-degree angles. Contractors use it to ensure cabinetry, shelving, and electrical fixtures align correctly over long spans. The compact frame allows for one-handed operation and easy transport between different zones of a project. It eliminates the need for manual spirit levels on large wall surfaces, significantly reducing layout time for solo operators. The internal pendulum levels the lines automatically within seconds, ensuring the reference remains true even if the mounting surface is slightly uneven.
