Hangers are required for headers if the span exceeds what distance?

Hangers are critical components in ensuring the structural integrity of headers, especially in residential construction. When the span of a header exceeds 6 feet, the use of hangers becomes essential to provide adequate support and to properly transfer loads. This requirement is based on structural engineering principles that take into account the potential for sagging and deflection over longer spans, which can compromise the stability and safety of the structure. By utilizing hangers in these cases, builders can enhance the overall strength and performance of the framing system.

The thresholds of 4 feet, 5 feet, and 7 feet are not aligned with the standard building codes that dictate when hangers are necessary. A span of 6 feet is recognized as a critical point where additional support is needed to ensure compliance with safety regulations and to mitigate structural issues. Therefore, the requirement for hangers at this span reflects best practices in construction and reinforces the importance of adequate support in framing applications.
