K2 Systems SingleHook 3S – Your Reliable Roof Hook for PV Installation
The **SingleHook 3S from **K2 Systems GmbH** is specifically designed for **photovoltaic mounting systems** on pitched roofs. It combines high flexibility, stability, and compatibility with the well-known **K2 mounting system** components – ideal for integration into K2 SingleRail or CrossRail installations.
With its triple height adjustment (40 / 47 / 54 mm), the roof hook can be precisely adapted to different roof structures and rafter heights. This allows installation even on narrow rafters starting from 36 mm – preferably from 48 mm. The adjustable base plate and the pre-assembled K2 Climber 36/50 make installation efficient and secure.
The material made of aluminum (EN AW‑6063 T66) and stainless steel (A2‑70) ensures high corrosion resistance and durability – perfect for outdoor use over many years. The hook is designed to meet the known requirements for static load, wind, and snow loads.
The installation is done directly on the rafter, with the SingleHook 3S being compatible with both K2 **SingleRail** and **CrossRail**. It comes with mounting material included and is part of the modular **K2 roof hook** system. Optionally, a **K2 lightning protection clamp** can be used to integrate lightning protection according to standards.
The triple height adjustment allows for flexible height compensation – for example, in case of irregularities in the roof space. Additionally, the height range can be further optimized with **K2 spacer plates** (e.g., 2 mm plates).
The SingleHook 3S is ideally suited for small to medium-sized PV systems on individual residential homes, where reliable and flexible **solar mounting** is required. Thanks to the close integration with other K2 components – such as **K2 rail**, K2 module mounts, or **K2 Minirail** systems – it seamlessly fits into your **K2 PV mounting** system.
