What is the required height for the center line of the top rail of a guardrail?

The required height for the center line of the top rail of a guardrail is typically between 36 inches to 45 inches above the walking surface. This height ensures that the guardrail is effective in preventing falls and protecting individuals in various settings, such as construction sites or elevated platforms.

Maintaining this height is crucial, as it strikes a balance between being high enough to provide safety and low enough not to interfere with normal use or access to an area. Additionally, building codes and safety standards often specify these dimensions to standardize safety measures across different environments, ensuring that the guardrails serve their purpose effectively.

By adhering to this established height range, it also helps in compliance with safety regulations, thereby reducing the risk of accidents and enhancing overall safety in construction and work environments.
