The SnapNrack 242-02073-USA Ultra Rail End Clamp Black is a domestically manufactured, universal end clamp tailored for the Ultra Rail system, securing the outer edges of solar modules with reliable bonding, structural strength, and a premium black aesthetic for residential and light commercial rooftop installations.
Key Features
- Compatibility: Universal design accommodates solar modules with frame thicknesses from 30 mm to 46 mm (standard range per SnapNrack specifications), fully compatible with UR-40 and UR-45 Ultra Rail profiles for consistent performance across the system.
- Finish: Black anodized or coated finish delivers outstanding corrosion resistance, UV durability, and a sleek, low-visibility appearance that complements black-framed modules and modern roof aesthetics for a polished, discreet solar array.
- Material: Constructed from high-strength 6000 series aluminum with stainless steel hardware, ensuring exceptional durability, load-bearing capacity, and long-term reliability in exposed conditions.
- Weight: Extremely lightweight at only 0.16 lbs per clamp, reducing overall system weight and making it easy to handle and install.
- Dimensions: Compact profile (approximately 1.57″ L x 1.03″ W x 2.73″ H or similar per engineering data), with a design that supports high structural loads while maintaining a low-profile look.
- Installation: Features SnapNrack’s signature snap-in mechanism for fast, tool-efficient attachment (typically using a 1/2″ or 13 mm socket); torque values align with system standards (e.g., 8-10 ft-lbs for black hardware), enabling quick module edge securing and integrated electrical bonding without additional components in many code-compliant setups.
- USA Domestic Content: The “-USA” designation indicates enhanced U.S. sourcing and manufacturing, meeting FEOC (Foreign Entity of Concern) compliance and qualifying for the ITC Domestic Content Bonus Credit (up to 10% additional incentive under the Inflation Reduction Act), perfect for projects focused on American-made materials and supply chain security.
Benefits and System Integration
As an essential part of SnapNrack’s Ultra Rail Roof Mount System, this black end clamp provides:
- Secure edge retention and built-in bonding for electrical continuity and code compliance across the array.
- Rapid deployment — snap-in design minimizes labor while preserving the system’s large-span capabilities and adaptability to various roof types.
- Superior aesthetics — black finish reduces visual contrast under the modules, delivering a cleaner, more professional installation.
- Seamless coordination — Integrates flawlessly with other black Ultra Rail components (rails, mid clamps, splices, L-feet, and flashings) for a fully matched system with concealed wire management and enhanced curb appeal.
It ensures reliable, high-performance module fastening that meets or exceeds building codes for wind, snow, and seismic demands in moderate to high-load areas.
Ideal Applications
Ideal for residential rooftop solar arrays featuring black-framed modules, where installers value fast installation, premium black aesthetics, domestic content incentives, and dependable edge clamping on diverse roof types.
