5.2 QRail Preparation <br /> The QRail external and internal QSplices are used to join two rail <br /> sections to provide a single rail section of a desired length. <br /> External QSplice Installation - <br /> ■ Forthe Heavy or Standard rails,join the rail sections together <br /> by sliding the QSplice onto the end of the rail, leaving half the _ - <br /> length of the splice protrudingfrom the end of the rail. Image 5.2.1 <br /> ■ Tighten the splice bolt onto the rail end. Tighten to 12 ft-lbf <br /> (16 N-m). <br /> ■ Slide the other rail onto the splice and tighten the splice bolt --- <br /> to 12 ft-lbf 16N-m). WIN <br /> NOTE! <br /> The QRail Internal and External QSplices are Image 5.2.2 <br /> a "full-strength" splice. Once it is installed <br /> and tightened to the recommended torque <br /> specification, it forms an essentially unbroken <br /> rail <br /> It may speed installation to splice rails on the - <br /> ground and transport them to the roof in one <br /> piece for installation on the roof attachments. <br /> To allow for thermal expansion/contraction, I m age 5.2.3 <br /> spliced rail lengths should not exceed 45 feet <br /> without a thermal break of 1/2 in. or more. Do <br /> not install modules over this thermal break. <br /> • <br /> The outside edge of the <br /> ' QClick must be installed Image 5.2.4 <br /> • at least 1/2" from end or <br /> rail at a splice location. <br /> DANGER <br /> Spliced rails must have more than one <br /> ' support on both sides of the splice. <br /> • Splices cannot be used in cantilever <br /> areas. <br /> CAUTION <br /> B1 7.2.3-46 18 Jul-2019, Rev 4.2 <br />
