SOLARMOUNT by Unirac is one of the top choices among professionals for residential PV mounting applications. The system is designed for superior aesthetics and an easier, faster installation process. 

The PRO series splice bars are used to join standard SOLARMOUNT rails together and retain integrated bonding throughout the system. The pre-drilled splice bar, includes self-drilling screws. Integrated Bonding provides electrical bond from rail-to-rail, when used with all four screws, for rigid joints. May be installed with screws on one rail only, for a sliding thermal expansion joint. (Sliding joints will require a bonding jumper.)
