RailUp for BasicRail

We recommend using this component in very warm regions or to optimise module performance. RailUp is supplied as a set and does not require any additional material for installation.

PVX Minimount

Our well-suited Performa mesh trays are high quality and rust-free. Installed without tools, secure, galvanically isolated cable ducting can be ensured.

Mounting on sandwich panels

The direct connection of the BasicRail with BasicClips and self-tapping screws on sandwich panels means that less time is required for installation. This results from the high installation speed of the BasicRail system and the direct fastening of the system in the sandwich panels.

Some sandwich manufacturers have granted approvals for this type of installation or have obtained German approval.
