An L foot is a critical component in solar panel installations. It connects the solar panel frame to the mounting rails. Typically made of extruded aluminum, the L foot includes an EDPM rubber pad, a tilt-in module, a socket head screw, and one TEK screw. It’s designed to work with specific rails and provides extra sealing to avoid galvanic corrosion. The number of L feet needed depends on your array and layout.
