What is the recommended tool for ensuring the correct alignment of corner blocks in a masonry wall?

The recommended tool for ensuring the correct alignment of corner blocks in a masonry wall is the masons level. This tool is specifically designed for checking the level and plumb of masonry work, which is critical in ensuring that walls are built true and square. The masons level typically has a long body, allowing the user to assess larger sections of masonry at once, and it features vials for both horizontal and vertical alignment.

Using a masons level helps ensure that each block is properly aligned with the others, contributing to the overall structural integrity and aesthetic of the wall. Proper alignment minimizes the risk of structural issues and makes finishing work, such as pointing or plastering, easier and more uniform.
