L-FOOT WITH ECO-FASTEN
The SolarCity L-Foot with Eco-Fasten QuikFoot optimizes strength, performance and aesthetics while
structurally attaching solar panels to composition shingle roofs. This engineered connection uses Eco-
Fasten's "QuikFoot" technology to achieve a robust, watertight connection. Stainless steel baseplate
combined with 6000 series aluminum L-Foot offers superb structural and fatigue strength, which in
conjunction with anodization offers excellent corrosion resistance even in coastal environments.
• Allows for 2 screws per standoff
• Anodized L-Foot for longterm corrosion resistance and best aesthetics
• No shingle cutting required
• Fast and error -proof installation reduces overall impact on roof
• Compatible with SolarCity Canopy Rail
• Rail is attached using Stainless Steel Fasteners
