Product Overview

The IronRidge XR-100-168B is a 168-inch (14-foot) black anodized aluminum solar mounting rail from IronRidge's XR100 Series — the heavy-duty tier of IronRidge's industry-leading XR roof-mount racking platform. At 2 inches wide and 8.5 lbs per 14-foot section, the XR100 is IronRidge's highest-capacity rail profile, engineered for longer spans, higher wind and snow load zones, and larger commercial residential arrays where the lighter XR10 profile's moderate load rating is insufficient. The black anodized finish delivers the same corrosion resistance and structural longevity as IronRidge's standard mill-finish rails — with the additional aesthetic benefit of a low-visibility, low-reflectance black surface that blends with dark-frame modules and modern rooflines for a clean, minimal visual profile. Like all XR Series rails, the XR-100-168B integrates with IronRidge's UL 2703 listed bonding and grounding system, ships with access to pre-stamped PE engineering letters for most U.S. states, and is fully supported by IronRidge's free online design software for site-specific structural calculations and permit-ready bill of materials generation. Backed by IronRidge's 20-year product warranty.

Key Benefits

XR100 Heavy Profile — Extended Span & High-Load Capability: The XR100 is IronRidge's heaviest and structurally strongest rail profile, designed for installations where attachment spacing exceeds the XR10's 6-foot moderate-load span limit, or where site-specific wind and snow load calculations require greater bending stiffness. The XR100's wider, deeper cross-section places significantly more aluminum mass away from the neutral bending axis — delivering a higher moment of inertia and therefore greater resistance to deflection under distributed panel loading than the XR10 at equivalent span lengths. For high-wind coastal regions, heavy snow load zones, or commercial-scale residential arrays with wide rafter spacing, the XR100 is the correct rail selection.

Black Anodized Finish — Aesthetic Integration with Dark-Frame Modules: The black anodized finish of the XR-100-168B is a hard-anodized aluminum oxide layer — not paint or powder coat — applied directly to the aluminum substrate through an electrochemical process that converts the surface aluminum to aluminum oxide (Al₂O₃). This produces a finish that is integral to the metal itself, not a surface coating that can chip, peel, or delaminate. Black anodized rails visually disappear beneath the dark frames and black backsheets of modern bifacial and all-black modules, reducing the visible racking footprint and improving the overall aesthetics of the completed array for homeowners who prioritize appearance.

UL 2703 Integrated Grounding — No Separate Grounding Hardware: The XR-100-168B integrates with IronRidge's UL 2703 listed bonding and grounding system, establishing the module-to-rail and rail-to-structure electrical bonding path through the UL-listed UFO clamps and attachment hardware — eliminating separate grounding lugs, WEEB washers, or inter-module bonding jumpers at every module position. This satisfies NEC 2020 §690.43 module bonding requirements without supplemental equipment, reducing both installation labor and material cost per module position across the full array.

Framed & Frameless Module Compatibility: The XR100 rail's continuous T-slot channel accommodates IronRidge UFO end and mid clamps for standard aluminum-framed modules, as well as IronRidge's frameless module clamp hardware for glass-on-glass bifacial and frameless module designs — making the XR-100-168B a single rail solution for installers who work across multiple module product lines or specification projects requiring frameless high-efficiency panels.

Pre-Stamped Engineering Letters — Faster AHJ Permit Approval: IronRidge provides pre-stamped (PE wet-signed) engineering letters covering XR Series installations across most U.S. states, allowing permit packages to be submitted without project-specific structural engineering for standard residential and light commercial applications. Combined with IronRidge's free online design software, a complete AHJ-ready permit package — including stamped engineering letter, site-specific load calculations, and full optimized bill of materials — can be generated and printed within minutes of entering site parameters.

Corrosion-Resistant for Coastal & High-Humidity Environments: Black hard-anodized aluminum provides exceptional corrosion resistance in salt-air coastal environments, high-humidity climates, and industrial areas with airborne chemical exposure — environments where painted or powder-coated finishes can blister, and where unfinished mill aluminum can develop cosmetic oxidation. The anodized oxide layer is non-reactive to most environmental conditions encountered in rooftop solar applications and requires no maintenance, refinishing, or re-coating throughout the 20-year warranty period.

How It Works

The XR-100-168B rail installs as part of IronRidge's complete XR Series racking system. Roof attachments — FlashFoot2 for composition shingle, Slotted L-Feet for metal roofs, or tile hook variants for tile roofs — are fastened to rafters at the spacing determined by the IronRidge design software's site-specific structural calculation. The XR100 rails are then seated onto the L-Feet and locked into position, and solar modules are mounted to the rails using IronRidge UFO end and mid clamps. The UL 2703 integrated bonding path is established through the clamp contact surfaces, eliminating separate grounding hardware at every module position.

Roof Attachment & Rail Leveling: IronRidge Slotted L-Feet provide up to 1.5 inches of vertical height adjustment at each attachment point, allowing the XR100 rail to be leveled across the full array plane without shimming — critical for black rail installations where any visible rail height variation is more apparent against dark-frame modules than on mill-finish installations. The T-bolt and nut system locks each L-Foot-to-rail connection at the correct height before module installation begins.

Rail Splicing for Long Array Runs: For array configurations requiring continuous rail runs longer than 168 inches, IronRidge XR splice bars join two XR100 rail sections end-to-end at a structural support point — maintaining full structural rail capacity across the splice joint. The 168-inch length is optimized for the most common residential portrait-layout array configurations and minimizes field cut waste. Black splice bars are available to maintain visual consistency with the black anodized rail finish across the full array.

Module Mounting with UFO Clamps: IronRidge UFO (Universal Frame Opening) end and mid clamps slide into the XR100 rail's continuous T-slot channel and can be positioned at any point along the rail length to accommodate any module frame width or array row spacing without drilling. Black UFO clamps are available to match the XR-100-168B's finish for a fully monochromatic black racking appearance. The clamp-to-module-frame and clamp-to-rail contact completes the UL 2703 bonding path from each module frame to the rail and through to the roof structure ground.

Customer Success Stories

EG4 off-grid base kit, Happy with my purchase.

This is the first stage of my three planned purches. I got the eg4 inverter 6000 XP base kit with six 400 watt panels and the two server rack batteries. Did a little online research and followed the instructions and it got set up without any issues. Right now I'm just running it in my garage on a single outlet and have been running dual 750 watt water distillers with it. Once I get the second inverter and a bunch more panels and batteries, I plan on attaching it to my subpanel in my house that has my lights and outlets and appliances on it. Then I'll get a soft start for my AC and blower and run it on my main panel.

Easy Process, Genuine Support

Trying to pick the correct solar system for your needs can be very technical and frustrating. I wanted to thank Yvhan and the Portlandia Electric supply team for their patience and helpful attitudes through multiple calls. I feel like we were able to narrow it down to what worked for me and my family. My system works great and I couldn't be happier to have picked Portlandia Electric Supply.

Patrick B

Off Grid Solar Purchase

I wanted to get an offgrid solar system for years but didn’t know where to start. I found Portlandia Electric Supply on Facebook and decided to submit a quote. Within 24 hours I had a custom proposal that was almost half the price of the companies I had previously got quotes from. My wife and I decided to order online and the kit came in a timely manner and it was an easy install. Great company to work with!

James Martin
