UNIRAC RLSPLCM2-US NXT Domestic Content Rail Splice

The Unirac RLSPLCM2-US NXT UMOUNT Rail Splice is a high-performance, 6-inch structural internal splice designed for the NXT UMOUNT rail-based racking system. Engineered for residential and commercial pitched-roof solar installations, this domestic-content component joins, aligns, and electrically bonds rail sections into a continuous, structurally sound run. Key Features & Benefits: True Structural Integrity: Fully structural internal splice provides load-rated performance, including cantilever installations. No additional roof attachments required at splice locations. Non-Interfering Design: Installs anywhere within the rail span without interfering with roof attachments or module clamps. PV modules and clamps can be placed directly over splice joints. Integrated Bonding: Delivers electrical bonding continuity across the splice, supporting UL 2703 system grounding and bonding requirements. Easy Installation: Pre-assembled with etched alignment indicators and uses bolts for secure connections. Streamlines on-roof assembly and reduces overall attachment count.
