How many inches must a shield plate extend above and below the sole and top plate for concealed piping protection?

In construction and plumbing practices, shield plates are essential for protecting concealed piping from physical damage, particularly when it comes to framing and wall installations. The requirement for shield plates to extend 4 inches above and below the sole and top plates is established in building codes and plumbing regulations.

This extension is crucial because it ensures that there is adequate coverage and protection for the piping, which might be vulnerable to impact or crushing if not properly shielded. By having the shield plate extend a sufficient distance above and below these critical areas, it provides a reliable safeguard for the pipes running through the walls.

This specification reflects a balance between practical protection and the limitations of material costs and installation complexity. Any lesser extension might not offer enough coverage to protect against various types of potential damage during construction or subsequent usage.
