K2 Systems CrossRail 80 Aluminum Solar Panel Mounting Rail

Heavy-Duty Solar Racking Rail for Ground-Mounted PV Systems

Structural Aluminum Rail | Mill Finish | CrossRail Ground Mount Compatibility | Modular Solar Racking
The K2 Systems CrossRail 80 is a heavy-duty aluminum solar mounting rail engineered to support photovoltaic modules in compatible ground-mounted solar racking systems. Featuring a tall structural profile and durable extruded aluminum construction, this rail provides dependable support for residential and commercial solar arrays.

Designed primarily for K2 Systems CrossRail Ground Mount applications, the rail integrates with compatible module clamps, rail connectors and ground-mount attachment hardware to create a secure solar panel support structure.

Its mill-finish aluminum construction offers a practical, professional solution for installers building ground-mounted photovoltaic arrays.

Key Features and Benefits

• Heavy-duty structural profile: Designed for solar mounting applications requiring a taller, more robust rail.
• Extruded aluminum construction: Provides structural strength with corrosion-resistant material characteristics.
• Ground-mount compatibility: Designed for integration with the K2 CrossRail Ground Mount System.
• Mill finish: Natural aluminum appearance without a dark anodized coating.
• Modular installation: Works with compatible K2 rail connectors and mounting accessories.
• Secure module attachment: Accepts approved K2 mid clamps and end clamps.
• Flexible array design: Supports professionally engineered solar panel layouts.
• Installer-friendly system: Integrates with K2's established solar mounting hardware ecosystem.
• Residential and commercial applications: Suitable for appropriately engineered photovoltaic mounting structures.

Heavy-Duty Support for Ground-Mounted Solar Arrays

The CrossRail 80 features a taller aluminum profile designed for the structural demands of compatible solar ground-mount installations.

Compared with lower-profile CrossRail options, its larger profile makes it particularly suited to K2's ground-mount system.

When incorporated into an appropriately engineered mounting assembly, the rail supports solar modules and transfers structural loads through the mounting hardware to the supporting structure.

Structural Mounting Benefits

• Provides a stable mounting surface for compatible solar modules.
• Integrates with K2 ground-mount support components.
• Supports modular photovoltaic array layouts.
• Allows installers to use manufacturer-matched clamping hardware.
• Offers a durable aluminum alternative to improvised mounting rails.

Durable Extruded Aluminum Construction

The CrossRail 80 is manufactured from structural aluminum with a natural mill finish.

Aluminum offers favorable strength-to-weight characteristics and inherent corrosion resistance, making it a practical material for outdoor solar mounting structures.

The extruded profile is designed to integrate with compatible K2 mounting components, allowing installers to build a coordinated solar racking system.

Material Advantages

• Structural aluminum construction.
• Corrosion-resistant material properties.
• Natural mill-finish appearance.
• Compatible with approved K2 hardware.
• Designed for long-term outdoor solar applications.

Compatible with K2 CrossRail Ground Mount Components

The CrossRail 80 is part of K2 Systems' modular solar mounting product family.

It can be paired with approved components from the CrossRail Ground Mount System to create a complete photovoltaic support assembly.

Compatible Component Categories

• CrossRail mid clamps: Secure adjacent solar module frames.
• CrossRail end clamps: Secure modules at the ends of a mounting row.
• CrossRail 80 rail connectors: Join compatible rail sections where permitted by the system design.
• Ground-mount brackets: Connect the rail to approved supporting hardware.
• Grounding and bonding accessories: Support electrical bonding when installed according to the approved system instructions.

Clamps, rail connectors, structural supports and grounding accessories are selected separately unless specifically included in the purchased package.

Designed for Professional Solar Installation

The CrossRail 80 provides installers with a standardized mounting rail designed to work within K2's engineered racking systems.

Its compatible accessory ecosystem helps simplify component selection and installation planning for ground-mounted photovoltaic arrays.

Installation Considerations

• Use K2-approved mounting brackets and structural supports.
• Verify rail spans against the applicable engineering documentation.
• Confirm module dimensions and approved clamping zones.
• Use the specified rail connectors when joining rail sections.
• Follow the manufacturer's grounding and bonding requirements.
• Account for local wind, snow and site-specific structural loads.
• Follow current K2 installation instructions and applicable building codes.

Ideal Applications

• Residential ground-mounted solar arrays.
• Commercial photovoltaic ground-mount systems.
• Solar installations using compatible K2 CrossRail support structures.
• Solar array expansions requiring matching CrossRail components.
• Contractor and professional installer projects.
• Replacement rail sections in compatible existing installations.

Product Specifications

Important Compatibility and Ordering Information

This listing is for the CrossRail mounting rail only, not a complete solar racking kit.

Compatible module clamps, rail connectors, brackets, ground-mount supports and grounding components must be selected according to the installation design.

Before ordering, confirm that the rail matches the intended K2 mounting system and that the proposed support spacing and loading meet the manufacturer's engineering requirements.

Structural capacity depends on the complete mounting configuration, not the rail alone.
