The SnapNrack 242-01220-USA Ultra Rail Umbrella L-Foot Black is a premium, domestically manufactured roof attachment component designed for the Ultra Rail system, specifically optimized for composition shingle roofs. This black-finished L-foot pairs with SnapNrack’s patented Umbrella Flashing (sold separately) to deliver a watertight, long-lasting, and aesthetically pleasing mounting solution for residential and light commercial solar installations.
Key Features
- Purpose and Compatibility: Serves as the structural base that attaches directly to the roof deck/structure and connects to UR-40 or UR-45 Ultra Rail profiles. It integrates seamlessly with the Umbrella Flashing system for superior waterproofing on comp shingle roofs.
- Finish: Black anodized or coated finish provides excellent corrosion resistance, UV stability, and a low-profile, modern appearance that blends discreetly with darker roof shingles and black-framed solar modules for enhanced curb appeal.
- Material: High-strength 6000 series aluminum construction (with stainless steel hardware included), ensuring durability, strength, and reliable performance in harsh outdoor conditions.
- Patented Umbrella Design Integration: Features a specialized design to accommodate the Umbrella Flashing and Umbrella Washer/Lag (sold separately or in kits), creating a raised “umbrella” seal that sheds water effectively and prevents leaks over the system’s lifetime—without requiring messy additional sealants.
- Weight: Ultra-lightweight (typically under 1 lb per unit; exact per engineering docs), reducing roof load and simplifying handling/installation.
- USA Domestic Content: The “-USA” designation confirms enhanced U.S. sourcing and manufacturing, qualifying for FEOC compliance and the ITC Domestic Content Bonus Credit (up to 10% additional incentive under the Inflation Reduction Act), supporting American-made projects and supply chain goals.
- Hardware: Includes necessary fasteners for rail attachment; pairs with compatible lags/flashings for a complete, code-compliant penetration.
Benefits and System Integration
Part of SnapNrack’s Ultra Rail Roof Mount System, this black Umbrella L-Foot offers:
- Watertight performance via patented Umbrella technology for reliable, long-term sealing on composition shingle roofs.
- Speed and simplicity — quick alignment to rail, one-tool installation in many cases, and drop-in compatibility with Ultra Rail’s open-channel design.
- Aesthetic and functional excellence — black finish minimizes visual impact while maintaining structural integrity and large-span capabilities.
- Full system coordination — Works perfectly with other black Ultra Rail components (rails, splices, clamps, flashings) for a unified, professional installation with concealed wire management.
It supports secure, low-profile mounting that meets or exceeds building codes for wind, snow, and seismic loads in moderate regions.
Ideal Applications
Best suited for residential rooftop solar arrays on composition shingle roofs where installers prioritize ease of installation, superior waterproofing, domestic manufacturing incentives, and a sleek black aesthetic to match modern module frames and roof lines.
