Which term refers to bricks laid on their narrowest edge, with the short end exposed?

1. Rowlock course

2. Soldier course

3. Header course

4. Stretchers course

The correct answer is: Rowlock course

The term that refers to bricks laid on their narrowest edge, with the short end exposed, is indeed a rowlock course. In this configuration, the bricks are positioned so that their ends, or "headers," are visible above the course line, contrasting with other laying patterns where bricks might be laid flat with the longer face exposed. Using this approach helps in various construction scenarios, especially to create decorative effects or to support specific architectural elements, such as arches and openings. It's distinctive because it provides a different visual texture and structural function compared to other courses, such as a soldier course, where bricks are laid vertically, or a stretcher course, where they are laid flat with the long side exposed. This knowledge of different brick-laying techniques is essential for those in construction and architectural design, as each term describes a specific method that serves both aesthetic and structural purposes. Understanding these terms aids in correctly interpreting construction documents and executing bricklaying tasks effectively.
