Unirac: SolarMount Splice Bars, Standard Rail Cat. No. UNI-3102xx Weight 10 lbs

Splice bars are used to join together lengths of SolarMount Standard Rail, SolarMount Light Rail.  Splice plates are also structural and may be used only with SolarMount  Standard Rail.   Neither type  creates a joint that is as strong as the rail itself.  A rail should always be supported by more than one footing on both sides of the splice. Expanion joints allow for thermal expansion and may be neccessary when rails exceed 30 feet.  Only splice bars may be used for thermal expansion joint  To create  an expansion joint, slide the splice bar into the footing slots of booth rail lengths  Leave a half inch between the segments.  Secure the splice bar with two screws on one side only.  Footings (such as L-feet or standoffs) should be secured normally on both sides of the splice.  NO PV module should straddle the expansion joint.
