Description
Productinformation in detail
The TerraGrif K2SZ is a compact and technically sophisticated **lightning protection and equipotential bonding clamp** made of stainless steel, developed by **K2 Systems GmbH**. It is specifically designed to create a secure connection between the module frame and mounting rail within the **K2 mounting systems**, thereby achieving compliant grounding.
In combination with **K2 roof hooks**, **K2 rail**, **K2 Minirail**, or other K2 substructures, the TerraGrif K2SZ is an essential component for a safe and durable PV installation. The clamp is mounted directly beneath the module frame, ensuring a robust electrical contact between the module and rail.
Thanks to its compact design and the material **stainless steel 301 TA**, the TerraGrif K2SZ is corrosion-resistant and durable. Its construction makes it particularly suitable for inclined roof systems. However, it is **not compatible with BasicRail in horizontal installation** (landscape orientation). Its easy installation perfectly complements the K2 mounting system portfolio and ensures safety according to standards.
Technical Specifications
GTIN / EAN: 4251786206889

Dimensions (W × H × D): approx. 10 × 16 × 60 mm
Material thickness: 0.5 mm
Use as lightning protection / grounding / equipotential bonding within K2 mounting systems
Compatible with: SingleRail, SolidRail, MultiRail, MiniRail, TiltUp systems (in inclined installation)
Not compatible: BasicRail in landscape (horizontal installation)
Functionality and Installation
The TerraGrif K2SZ is integrated directly under the module frame into the K2 rail, typically in the area of the lower module edge. The support under the module frame creates an electrical contact with the module, which, together with the connection to the rail, ensures the necessary equipotential bonding and grounding.
The installation is tool-assisted and easy to implement. Careful attachment is important to ensure secure contact and thus compliant function (e.g., according to VDE or local lightning protection regulations).
Application Areas and Advantages
Extension of existing **K2 solar and K2 mounting systems** with compliant lightning protection solution
Compatible with **K2 roof hooks**, **K2 rail**, **K2 Minirail**, and other system components
Minimal space requirement – integrates discreetly under module edges
Corrosion resistance thanks to stainless steel material
Easy installation without major extras
