What tool is typically used to ensure drywall panels are properly aligned and level during installation?

The tool used to ensure drywall panels are properly aligned and level during installation is a level. A level is crucial in this process because it allows the installer to check that the drywall is straight both horizontally and vertically. Achieving a level installation is essential for aesthetic purposes, as well as for the proper application of finishes and to avoid issues with the drywall bowing or cracking over time.

Using a level ensures that each panel fits snugly against adjacent panels, which is vital for creating a seamless look. When hung correctly, drywall panels have a significantly enhanced structural integrity, which is critical for the overall durability of the wall. While other tools like drills, saws, and measuring tapes are important in the installation process, they serve different purposes, such as fastening, cutting, and measuring, rather than ensuring alignment and leveling specifically.
