303002D SolarMount and SunFrame Serrated Splice Bar with Hardware - 20 Pack
Splice for SunFrame and SolarMount rail
The Splice Bar does not create 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. Expansion joints allow for thermal expansion and may be necessary 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 both 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.
