The Bonded L-feet is engineered for most roof mounting applications. Vertical slots allow for easily dropping in rails with pre-attached hardware and provide adjustability to account for roof irregularities. The L-feet are manufactured using 6000 series aluminum and are also available in a black anodized finish. Bonding hardware is needed to attach and bond the rail to the L-foot. Step nut allows installers to use the same socket as the rest of the system.
