Use at least two per <br />row of modules. Aluminum extrusion, available in <br />mill, clear anodized, or dark anodized. <br />RAIL SPLICE: Non structural splice joins, <br />aligns, and electrically bonds rail sections into <br />single length of rail. Forms a rigid splice joint, 4 <br />inches long, preassembled with bonding hardware. <br />Available in dark anodized or mill finish. <br />L-FOOT: Use to secure rails through roofing <br />material to building structure. Refer to loading <br />tables or U-Builder for spacing. <br />L-FOOT T- BOLT: (3/8” x ¾" or 1”) – Use one per <br />L-foot to secure rail to L-foot. Stainless steel. <br />Supplied with L-foot in combination with flange <br />nut, <br />provides electrical bond between L-foot and rail. <br />SERRATED FLANGE NUT : Use one per L-foot <br />to secure and bond rail to Lfoot. Stainless steel. <br />Supplied with L-foot. <br />MODULE ENDCLAMP: Pre-assembled universal <br />clamp that secures module to rail at module <br />flange by tightening 1/2" hex head bolt. <br />MODULE MIDCLAMP: Pre-assembled clamp <br />provides module to module and module to rail <br />bond. Aluminum clamp with stainless steel <br />bonding pins and T-bolt. Available in clear or <br />dark finish. <br />MICROINVERTER MOUNTING BOLT: <br />Preassembled bolt, nut, and captive star washer <br />attaches and bonds microinverter to rail. <br />NOTE - POSITION INDICATOR: T-bolts have a slot in <br />the hardware end corresponding to the direction of <br />the T-Head. <br />Wrenches and Torque <br /> <br />Stainless steel hardware can seize up, a process called <br />galling. To significantly reduce its likelihood: <br />1. Apply minimal lubricant to bolts only where <br />indicated in installation process, preferably Anti-Seize <br />commonly found at auto parts stores (Anti-seize has <br />been factory applied to mid clamp bolts) <br />2. Shade hardware prior to installation, and <br />3. Avoid spinning stainless nuts onto bolts at high speed. <br /> <br />See Appendix C for <br />Universal AF Installation* <br />See Appendix C for <br />Universal AF Installation*2110 W 7th St - <br />2017778512/28/22
