Ressistance factors and safety factors are determined <br />according to part 1 section 9 of the 2005 Aluminum Design <br />Manual and third-party test results from an IAS accredited <br />L-BRACKEY <br />NOTE: Loads are given for the L-bracket to rail connection only; <br />be sure to check load limits for standoff, lag screw, or <br />other attachment method <br />1% ROT FOR <br />Y <br />'LI <br />, Applied Load Average,Safety Design Resistance <br />Direction Ultimate Allowable Load Factor,Load Factor, <br />lbs (N)lbs (N)FS lbs (N) ® <br />.. <br />3.00 Sliding, Zi 1766 (7856)755 (3356)2.34 1141 (5077)0.646 <br />Tension, Y+1859 (8269)707 (3144)2.63 1069 (4755)0.575 <br />i . ,Compression, Y- 3258 (14492)1325 (5893)2.46 2004 (8913)0.615 <br />2.00 -Traverse, Xi 486 (2162)213 (949)2.28 323 (1436)0.664 <br />Dimensions specified in inches unless noted <br />SWH Solar Mount Splice Bar <br />Part No.MR-SW-SB-01, MR-SW-SB-018 <br />1 SELF-TAPPING SCREW <br />RAIL - <br />SPLICE <br />RAIL i. <br />. Splice bar material: 6005-T5 extruded aluminum alloys <br />• Maximum tensile: 38ksi, yield: 35ksi <br />. Finish: clear or black anodized <br />. Self-tapping screw material: 304 stainless <br />. Splice bar weight: 0.36 lbs <br />Allowable and design loads are valid when components are assembled <br />. according to authorized SWH documents <br />For the Splice bar to Rail connection: <br />• Slide splice bar in groove on between two rails <br />• Use 4-81/4" self-tapping screw to join Splice bar to both rails <br />. Ressistance factors and safety factors are determined according to part 1 <br />section 9 of the 2005 Aluminum Design Manual and third-party test <br />results from an IAS accredited laboratory <br />A thermal break is required every 40 feet of continously connected rail. <br />For additional concerns on thermal breaks in you specific project, please <br />consult a licensed structural engineer. <br />. Expansion joints prevent buckling of rails due to thermal expansion. <br />Splice bars may be used for thermal expansion joints. To create a thermal <br />expansion joint, slide the splice bar into the 1 /2" between the rail <br />segments. Secure the splice bar with two screws on one side only. Foot- <br />ings (such as L-brackets or standoffs) should be secured normally on <br />both sides of the splice. No PV module or mounting hardware component <br />should straddle the expansion joint <br />SPLICE BAR <br />r <br />-
