Company Overview
SnapNrack is headquartered at 775 Fiero Lane, Suite 200, San Luis Obispo, CA 93401. The company operates as a division of SunRun South LLC (DBA SnapNrack), making it one of the few racking manufacturers owned by a major solar installer. This connection to the installation workforce gives SnapNrack unique insight into the real-world challenges installers face on the roof, driving product development toward labor-reducing innovations.
SnapNrack's market position is defined by its installer-first design philosophy. The company was the first to bring preassembled clamp mounts to market, eliminating the need for installers to fumble with T-bolts and rail hardware on the roof. All roof attachments come rail-ready out of the box—simply lag in the mount and start dropping in rail immediately. The SnapNrack R&D test facility in Santa Cruz, CA is a qualified participant in the UL Data Acceptance Program, allowing the company to directly submit in-house UL 2703 testing results.
Current Product Lines
Ultra Rail System
The Ultra Rail is SnapNrack's flagship rail-based mounting system, available in two profiles:
- UR-40 Rail: Standard residential rail for most wind and snow conditions. Available in 132" and 168" lengths.
- UR-60 Rail: Heavy-duty rail for high-load applications. Available in 172" length.
The Ultra Rail system includes universal mid-clamps, end clamps, splices, ground lugs, and a full range of roof attachments. All hardware uses a consistent 1/2" socket connection throughout the system for tool simplicity.
TopSpeed Railless System
TopSpeed is SnapNrack's railless mounting solution, eliminating rails entirely for faster installation and a cleaner aesthetic. Modules are mounted directly to roof attachments using integrated clamping hardware. The system requires the Universal Landscape SkirtRail for a complete, code-compliant finish.
SkirtRail
The SkirtRail is a black anodized aluminum skirt that conceals module edges, wiring, and hardware for improved curb appeal. Available in landscape (70") and portrait (83") configurations. Compatible with both Ultra Rail and TopSpeed systems. Made in the USA from durable aluminum.

Series 100 & 200 (Legacy)
SnapNrack's Series 100 and 200 systems are legacy rail-based mounting systems that received updated UL 2703 listings in 2024, restructuring the grounding/bonding listing for improved ease of installation while maintaining strict compliance with UL 2703 test standards.

AnchorFoot Installation
The AnchorFoot is designed for installation on dry, clean surfaces at temperatures above 32°F. The butyl strip on the bottom of the foot provides the primary seal. For deck mounting, use DeckAnchor screws through the foot mounting holes. For rafter mounting, use a 5/16" lag screw (2.5" minimum embedment) plus 2 x #14 wood screws (1.25" minimum embedment) into the rafter. Tighten fasteners until butyl starts squeezing out from all sides. The AnchorFoot should never be installed across two shingle courses.
Frequently Asked Questions
1. What is the advantage of SnapNrack's preassembled Clamp Mounts?
SnapNrack's Clamp Mounts come preassembled to all roof attachments (UltraFoot, SpeedSeal, AnchorFoot, Tile Hooks), meaning the rail mounting hardware is already attached when you open the box. Installers simply lag the mount to the roof and immediately drop in the rail—no fumbling with T-bolts, no hardware falling off the roof. SnapNrack was the first company to bring this technology to market.
2. What is the TopSpeed railless system and when should I use it?
TopSpeed is SnapNrack's railless mounting solution that eliminates rails entirely, mounting modules directly to roof attachments. It reduces material costs, installation time, and visual profile. TopSpeed requires the Universal Landscape SkirtRail for code compliance. It is best suited for residential installations with consistent module layouts where the aesthetic and speed benefits outweigh the design flexibility of rail-based systems.
3. Can SnapNrack rails be used with Quick Mount PV mounts?
Yes. SnapNrack has explicitly stated support for using Series 100 Standard Rails and module mounting hardware with Quick Mount PV roof mounts, specifically their QBlock and QBase products. This cross-brand compatibility gives installers flexibility to pair SnapNrack rails with their preferred attachment solution.
4. What makes the Universal OmniBase different from other mounts?
The OmniBase is a truly universal mounting solution that works with 1 lag screw on rafters, 2-4 screws on flat or metal framing, or 6 screws for rafter-less surfaces. It includes built-in sealant pockets, anti-rotation features, and compatibility with common flashings and e-curbs. It comes preassembled with the Leveling Clamp for direct-to-rail mounting without an L-foot.
5. What warranty does SnapNrack offer and is it transferable?
SnapNrack offers a 25-year warranty under its "One Tool. One Warranty." program, covering the entire system—rails, mounts, clamps, and skirt—under a single manufacturer warranty. The warranty covers structural components against defects in materials and workmanship for the life of the solar installation.
