The GW 34 counter channel from Niedax is a mounting component for hammerhead strap clamps, specifically designed for the secure and durable installation of cables with a diameter of 30 to 34 mm. The product is made of polyethylene (PE), a robust plastic known for its chemical resistance and mechanical strength. The counter channel is black and features UV protection, ensuring long-term resistance to sunlight exposure. It is halogen-free and silicone-free, meaning it does not contain substances that could interfere with paint adhesion – an important property especially in applications where painting or coatings are present in the installation environment.

Applications

The GW 34 counter channel is used in electrical and IT installations where cables are mounted on C-profile rails. It is specifically intended for hammerhead strap clamps of types B and BK, which are commonly used in industrial and commercial electrical engineering. Installation is carried out on C-profile rails with a slot width of 16 to 17 mm. The self-clamping spring clip allows for easy and quick mounting without additional tools. The operating temperature range extends from -40 °C to +80 °C, enabling use in a wide range of environments, including outdoor areas or industrial facilities with temperature fluctuations.

Functions and Features in Detail

The counter channel is equipped with a spring clip that enables self-clamping mounting on C-profile rails. This design ensures a secure and slip-resistant anchoring without requiring additional fastening elements such as screws or bolts. The shape of the counter channel is tailored to cable diameters of 30 to 34 mm, ensuring optimal fit and even pressure on the cable. The length is approximately 40 mm, sufficient to maintain stable cable fixation.

Technical Explanation

The material polyethylene (PE) offers high mechanical strength and is resistant to moisture, chemical influences, and UV radiation. The silicone-free formulation prevents the counter channel from impairing surfaces when in contact with paints or coatings. The halogen-free composition reduces the formation of toxic fumes in case of fire, enhancing safety during use. The self-clamping spring clip enables quick, tool-free installation, making the installation process more efficient.

Compatibility and Accessories

The GW 34 counter channel is specifically designed for hammerhead strap clamps of types B and BK. Compatible accessories include the universal counter channel 2058UW 34 LGR in light grey, suitable for cable diameters of 28 to 34 mm, as well as the hammerhead strap clamp BK34, intended for cables with a diameter of 30 to 34 mm. The combination of these components enables modular and flexible cable mounting on C-profile rails.

Installation and Mounting

Installation is performed by simply inserting the counter channel into the C-profile rail. The integrated spring clip ensures the counter channel remains securely anchored in the slot. Subsequently, the hammerhead strap clamp is inserted over the counter channel and the cable is fastened. The installation requires no tools and can be carried out quickly and without additional aids.

Operational Advantages

The GW 34 counter channel provides a reliable and durable cable fixation solution for industrial and commercial facilities. The UV- and chemical-resistant surface ensures long service life, even under demanding operating conditions. The tool-free installation reduces installation time and labor effort. The halogen-free and silicone-free composition enhances safety and prevents unwanted interactions with surrounding materials.
