What is the purpose of rowlock bricks in masonry?

Rowlock bricks are specifically designed to span openings in masonry construction. When installed horizontally, they are placed on their narrow face, allowing them to effectively support weight above doorways, windows, or other openings. Their positioning ensures that the load from the brickwork above is evenly distributed across the span, providing strength and stability to the overall structure.

This usage is crucial in masonry since spanning openings correctly is essential for maintaining the integrity of the wall and preventing structural issues. Rowlock bricks also contribute to the aesthetics of a wall by creating a finished edge around these openings.

While rowlock bricks can have decorative aspects or may be involved in structural considerations, their primary function is directly related to spanning openings, which is a fundamental aspect of masonry design and construction.
