The GW 22 counter channel from Niedax is a mounting component for hammer-head cable clamps, specifically designed for use with cables having a diameter range of 18 to 22 mm. It serves as an additional component for secure and durable cable fixation to C-profile rails, particularly in industrial or technical installations where stable and resilient anchoring is required. The counter channel is self-retaining and mounted onto C-profile rails with a slot width of 16 to 17 mm, with the clamp spring ensuring secure fixation. The material, polyethylene (PE), is silicone-free and thus suitable for applications where paint adhesion must not be impaired.

Applications

The GW 22 counter channel is used in electrical and IT installations where cables need to be secured to C-profile rails. It is particularly suitable for installations in production environments, buildings with industrial electrical installations, or technical rooms where high mechanical load capacity and weather resistance are required. The operating temperature range of -40 °C to 80 °C allows use in various climatic conditions, including outdoor areas, provided ambient conditions remain within this temperature range. The UV-protective coating increases resistance to sunlight exposure and prevents premature aging of the plastic material.

Functions and Equipment in Detail

The counter channel is specifically designed for use with hammer-head cable clamps of types B and BK. Its shape and clamp spring allow it to fit securely onto C-profile rails, enabling quick and tool-free installation. The self-retaining design ensures the counter channel sits securely on the rail without additional fastening elements. The black color makes it visually inconspicuous in technical installations. The halogen-free composition of the material reduces the formation of toxic fumes in case of fire, enhancing safety during use.

Technology Explained Simply

The counter channel is made of polyethylene, a robust and durable plastic known for its chemical resistance and mechanical strength. The clamp spring ensures the counter channel sits elastically on the C-profile rail and adapts to the rail’s shape. The UV-protective coating prevents the surface from becoming brittle or discolored due to sunlight exposure. The silicone-free formulation is important to avoid impairing paint adhesion when mounting on painted surfaces. The operating temperature range of -40 °C to 80 °C makes the product suitable for a wide range of environments, from cold storage rooms to warm production halls.

Compatibility and Accessories

The GW 22 counter channel is specifically designed for hammer-head cable clamps of types B and BK. Compatible accessories include the hammer-head cable clamp BK22 for cables with a diameter of 18 to 22 mm, which is also hot-dip galvanized, as well as the universal counter channel 2058UW 22 LGR in light gray, suitable for cable diameters of 16 to 22 mm. Combining these clamps enables flexible and secure cable fixation to C-profile rails. The counter channel is not intended for other clamp types or rail profiles that do not have the specific slot width of 16 to 17 mm.

Installation and Mounting

Installation is tool-free and involves simply snapping the counter channel onto the C-profile rail. The clamp spring ensures secure anchoring, with the counter channel adapting to the rail’s shape. Installation is performed in combination with a hammer-head cable clamp, which is also mounted onto the rail. The counter channel is positioned to support the cable clamp from the opposite side, ensuring stable cable fixation. The mounting process is quick and requires no additional fastening elements.

Operational Advantages

The GW 22 counter channel provides a reliable and durable solution for cable fixation to C-profile rails. The self-retaining design reduces installation time and eliminates the need for additional fastening components. The UV-protective coating and operating temperature range of -40 °C to 80 °C increase product lifespan and operational safety. The halogen-free and silicone-free material composition ensures safe and environmentally compatible use, especially in sensitive applications such as electrical installations in buildings or industrial facilities. Combined with hammer-head cable clamps, it offers a flexible and modular fixation solution adaptable to various installation scenarios.
