The GW 30 counter channel from Niedax is a mounting component for hammer-head clamp brackets, specifically designed for use with C-profile rails. It serves as an additional component to securely and stably fix cables with a diameter of approximately 26 to 30 mm. The counter channel is mounted self-tightening onto the C-profile rail, with an integrated clamping spring ensuring the fastening. The product is made of polyethylene (PE), a robust plastic suitable for its resistance to mechanical stress and environmental influences. The colour is black, enabling unobtrusive integration into technical installations.

Mounting technology
The counter channel is mounted self-tightening onto C-profile rails with a slot width of 16 to 17 mm using a clamping spring. This design allows for quick and tool-free installation, making cable mounting on vertical or horizontal carriers more efficient. The clamping spring ensures a secure hold without requiring additional fastening means such as screws or adhesives.

Material and environmental resistance
The material polyethylene (PE) is silicone-free and free of substances that could interfere with paint adhesion. This property is particularly important in applications where the surfaces of installed components must not be damaged. Additionally, the product is halogen-free, resulting in lower environmental impact during processing and disposal. The counter channel features UV protection, ensuring long-term resistance to sunlight exposure and protecting the material against premature ageing.

Temperature resistance and application areas
The counter channel is designed for an operating temperature range of -40 °C to 80 °C, making it suitable for a wide range of indoor and outdoor applications. Its temperature resistance allows use in industrial environments where high or low temperatures may occur, as well as in buildings with climate-controlled rooms. The length of the counter channel is approximately 40 mm, providing sufficient coverage for most cable diameters within the specified range.

Compatibility and application
The GW 30 counter channel is specifically designed for hammer-head clamp brackets of types B and BK. It is used in combination with these brackets to securely fasten cables to C-profile rails. The application is in electrical and IT installations, particularly for cable routing in racks, server rooms, or industrial facilities. The combination of counter channel and clamp bracket enables orderly and neat cable management.

Operational benefits
Thanks to the tool-free installation and secure fastening via clamping spring, installation time is reduced. The material quality and UV and temperature resistance ensure a long service life and low maintenance requirements. The halogen-free and silicone-free composition of the material protects installed surfaces and contributes to a safe working environment. The counter channel is thus a reliable component for professional cable fastening in technical installations.
