Unirac #310230 - Splice Bar for SolarMount & SunFrame Rails
Please
Note- This 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 each side of the splice.
Order one splice bar per two segments to be joined into a single rail. Expansion joints allow for thermal expansion and may be necessary when rails exceed 30 feet. Only splice bars may be used as thermal expansion joints. 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.
