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.
- Domestic Content: Qualifies for Domestic Content Bonus Credit (DCBC) incentives when used per IRS guidelines.
- Durability: Mill-finish aluminum construction ensures long-term reliability in demanding environments (25-year warranty typical for Unirac components).
Specifications:
- Length: 6 inches
- Material: Aluminum (mill finish)
- Compatibility: NXT UMOUNT Standard and HD Rails
- Certifications: Part of UL 2703 / UL 3741 compliant system
Ideal for extending rail runs efficiently while maintaining structural performance, wire management, and system aesthetics. Perfect for installers seeking fewer parts, faster labor, and maximum design flexibility.
