What is the maximum sphere diameter that guardrail infill should not permit to pass through?

The maximum sphere diameter that guardrail infill should not permit to pass through is 4 inches. This standard is essential for ensuring safety, especially in areas where children might be present. The 4-inch measurement is based on the principle that any sphere that is 4 inches in diameter cannot fit through the guardrail infill, effectively preventing larger objects from passing through and minimizing the risk of accidents or falls.

The reasoning behind this specification relates to safety regulations that aim to protect individuals, particularly young children, from slipping through the gaps in guardrails. A sphere larger than 4 inches could allow a child's body part to pass through, which raises the potential for serious injuries.

In residential and commercial applications, adhering to this guideline ensures that the infill design remains compliant with safety codes, thus providing an adequate barrier while still allowing visibility and airflow.
