S4 Large Lateral Extension


The S4 Large Lateral Extension is designed to extend the lateral flashing or frame support in S4 roof-integrated mounting systems. It provides longer coverage where standard lateral flashing pieces are insufficient, enabling more flexible and complete edge sealing around large PV arrays. This extension maintains a weather-resistant perimeter while integrating seamlessly with the mounting system.
