The chalk lines will be <br />used to align TileTrac ® attachment points. <br />Note: All support rails should be placed 48” <br />apart along the module length. The rail dis- <br />tance from the end of the module will vary <br />based on module size. <br />The 48” grid design is based on 12”, 16” or 24” on center (o/c) rafter spacing. <br />(12” x 4 = 48”, 16” x 3 = 48”, 24” x 2 = 48”) <br />All product specifications are based on 48” paired support rail spacing. <br />Proper module/rail orientation—single array sample <br />Rafter Directio <br />n <br /> Supp <br />o <br />r <br />t Rai <br />l Direc <br />t <br />ion <br />Clamps must secure the module on the <br />long end of the frame.
