Unirac NXT Horizon 168" (14') Mill Finish Solar Mounting Rail 168RLM1

The Unirac NXT Horizon 168RLM1 is a mill-finish aluminum solar mounting rail designed for the Unirac NXT mounting platform. Unirac's current NXT UMOUNT documentation identifies 168RLM1 specifically as the NXT UMOUNT Rail – 168" Mill, while earlier NXT Horizon documentation identifies the same part number as the NXT Horizon Rail – 168" Mill. 

Designed for rail-based rooftop PV installations, the NXT platform uses a rail-clamp connection that provides flexibility across compatible roof attachments. Its click-in rail and clamp architecture is designed to streamline rooftop assembly while maintaining a structured mounting platform for compatible PV modules. 

Key Technology

• NXT Rail Platform
  Designed as the primary structural rail within compatible Unirac NXT rooftop solar mounting systems.

• Mill Finish
  Features Unirac's mill-finish configuration for applications where a natural aluminum appearance is preferred.

• Click-In Installation Architecture
  The NXT platform uses click-in rail and clamp connections designed to simplify component assembly and reduce installation steps on the roof.

• Flexible Roof Attachment Integration
  The rail-clamp connection enables the NXT rail to interface with a range of compatible Unirac roof attachment configurations, including applicable flashed and non-flashed attachment solutions. 

• Compatible Rail Splicing
  Designed to work with the corresponding NXT UMOUNT Rail Splice when properly engineered rail runs require rail sections to be joined. Unirac's current documentation identifies the compatible splice as RLSPLCM2.

• Integrated NXT Component Ecosystem
  Works as part of the NXT platform with compatible combo clamps, hidden end clamps, MLPE and grounding components, wire-management hardware, and roof attachment solutions.

Best Uses

• Residential Rooftop Solar
  Designed for properly engineered residential photovoltaic arrays using compatible Unirac NXT mounting components.

• Rail-Based PV Module Mounting
  Provides the structural rail interface required for compatible module clamps and roof attachment assemblies.

• New NXT Mounting Systems
  Suitable for new rooftop installations designed around the current compatible Unirac NXT mounting platform.

• Existing Compatible NXT Horizon Systems
  The 168RLM1 part number also appears in Unirac's earlier NXT Horizon documentation, making it applicable when this exact rail is specified for a compatible existing NXT Horizon installation.
