Schletter ProLine Internal Rail Connector Pro 129200-000

The Schletter ProLine Internal Rail Connector Pro 129200-000 is a dedicated joining component for the ProLine mounting rail system. Unlike generic connectors, it slides directly into the rail profile, creating a seamless structural transition between rail sections. This internal design maintains the clean exterior of the rail and ensures a continuous load path across the array.

Highlights

• Compatible with Schletter ProLine rails
• Internal mounting for a flush, unobtrusive connection
• Aluminium construction for corrosion resistance
• Mill finish matches standard rail aesthetics
• Compact 120 mm length for efficient splicing

In daily use

Installers align two ProLine rails end-to-end, slide the connector halfway into each profile, and secure it with fastening screws (not included). The result is a rigid, continuous rail that supports PV modules without visible external brackets. The aluminium body withstands outdoor exposure, and its dimensions (120 x 25 x 35 mm) are tailored to the ProLine profile.
