What tool is used to secure a masonry line to masonry units?

The use of a line block is essential in masonry work for securing a masonry line to the individual blocks or bricks. This tool helps to keep the masonry line taut and ensures that the level and alignment of the units being laid are consistent throughout the project. By providing a point to anchor the line, the line block allows masons to measure and maintain the correct height and spacing, which is crucial for achieving a well-structured and aesthetically pleasing finish.

Line blocks traditionally have slots designed to hold the line securely in place, which helps in guiding the placement of masonry units accurately. This tool is particularly important for larger masonry projects where maintaining the correct alignment over long distances is necessary.
