The weight of what object may be used to secure a twigged line?

Using a brick to secure a twigged line is a practical choice due to its balanced weight and manageable size. Bricks are typically dense and can provide sufficient weight to keep the line taut, which is important when establishing a clear guideline or level during masonry work. They are common materials on construction sites, making them readily available.

A concrete block, while heavier and possibly providing more weight, might be cumbersome to handle in situations requiring quick adjustments. Additionally, stone can vary significantly in size and weight, which may not make it the best choice unless specifically selected. Masonry units, being a broader category that includes bricks and blocks, might not specify the ease of use or handling needed for securing a line effectively. Thus, a brick stands out because it balances weight and convenience, making it suitable for the task of stabilizing a twigged line.
