S:FLEX LEICHTmount - Model RAIL 2.1 -Aerodynamic Flat-Roof Frames

The main advantages of the LEICHTmount RAIL 2.1 S/EW:

• Optimised rear ventilation for maximum energy yield
• Optimised cable management with conduit covers and edge clips
• Integrated cable ducts and covers that make cable routing possible even after system installation without additional expense or effort
• Integrated fall protection (optional)
• Roof drainage is ensured
• Capable of carrying lightning currents in accordance with DIN EN 62561 (VDE 185-561-1):2013-02
• We will gladly create the structural design for our customer's projects if required – the documentation we provide includes the structural analysis and the ballast plan

Components
LEICHTmount RAIL 2.1 S ground rail
Our ground rail with attached foot plates ensures even load distribution over the roof.

LEICHTmount RAIL 2.1 base
The base serves as a lower receptacle for modules and module clamps.

LEICHTmount RAIL 2.1 tower
The tower is clicked on the floor rail and serves as an upper receptacle for modules and module clamps

LEICHTmount RAIL 2.1 foot plate
Foot plates attached with a click to the ground rails to protect the roof skin from plasticizer migration.

End and mid clamps
S:FLEX module clamps have an extremely wide clamping area and are therefore suitable for all standard modules and frame heights of 30-50 mm. High torsion resistance and our latest, ultra-smooth one-click technology make installation a snap.

The lightweight alternative

Aerodynamic, lightweight and totally wind-safe installation possible without roof penetration. The S:FLEX LEICHTmount RAIL 2.1 mounting system for framed PV modules is the ideal solution for flat roofs – even with a low load-bearing capacity.

Both variants – the System S for the traditional south-facing orientation and the EW variant for maximum east/west coverage – deliver outstanding economy. The use of only a few, pre-assembled components, most of which can be connected easily and securely with one click, makes installation easy, efficient and fast. No need for time-consuming measuring, drilling or cutting on the roof.

In addition to the wide new foot plates clicked onto the substructure, the tool-free installation without self-drilling screws or sharp-edged components provides additional protection – even for the most delicate roof membrane.
