IronRidge’s Bonded L-feet are designed to work with most roof mounted solar systems. They are made with 6000 series aluminum and are available in mill or black anodized finish. The vertical slot across the surface of the L-foot allows for adjustments in the rail height to accommodate roof irregularities. The kit includes 1 L-Foot, hardware is not included. Use square bolt FM-SQ-BHW to attach it to the XR rails (see accessories below).
