The Niedax BK 22 is a hammer foot clamp designed specifically for securing cables with a diameter of 16 to 22 mm to C-profile rails with a slot width of 16 to 17 mm. The product consists of a hot-dip galvanized steel clamp, a polypropylene (PP) plastic pressure trough with UV protection, and an M 6 stud screw with multi-drive. The pressure trough is halogen-free and black in colour, enabling seamless visual and functional integration into industrial and technical installations. The trough insert is made of strip galvanized steel in accordance with DIN EN 10346, ensuring high corrosion resistance and mechanical stability.

Mounting technology

The hammer foot clamp enables secure and durable anchoring of cables to C-profile rails, commonly used in electrical installations, industrial plants, and building automation systems. The hammer foot design allows for easy mounting and secure fixation to rail profiles. The integrated M 6 stud screw with multi-drive ensures efficient and precise tightening, simultaneously securing the pressure trough and the cable. The polypropylene pressure trough protects the cable from mechanical stress and ensures even load distribution.

Materials and coating

The hammer foot clamp is made of steel and hot-dip galvanized in accordance with DIN EN ISO 1461, providing high corrosion resistance and longevity even in humid or industrial environments. The trough insert made of strip galvanized steel (DIN EN 10346) offers additional protection against rust and mechanical stress. The polypropylene plastic pressure trough is halogen-free and UV-protected, enhancing resistance to sunlight and weather influences. The black colour ensures discreet integration into technical installations.

Applications

The BK 22 is suitable for use in electrical installations, industrial plants, building automation systems, and other areas where cables need to be secured to C-profile rails. The clamp is particularly suited for cables with a diameter of 16 to 22 mm, with maximum load capacity ensured by the construction and materials. Use with C-profile rails having a slot width of 16 to 17 mm is intended, enabling universal applicability in standard installation systems.

Compatibility and accessories

Compatible counter troughs include, for example, the GW22 counter trough for hammer foot clamp for cable diameters 18–22 mm made of PE plastic, and the 2058UW 22 LGR universal counter trough for cable diameters 16–22 mm in light grey finish. These counter troughs complement the clamp and enable secure and tight cable fixation to the rail.

Installation and mounting

Mounting is performed by inserting the hammer foot clamp into the C-profile rail, with the screw passing through the pressure trough and the cable. The screw is then tightened using a suitable tool, causing the pressure trough to securely hold the cable. Use of a counter trough is necessary to ensure complete fixation. Installation requires no additional tools other than a screwdriver or a suitable drive tool for the M 6 screw.

Operational benefits

The BK 22 provides a reliable and maintenance-free cable securing solution for technical installations. The combination of hot-dip galvanized steel, UV-resistant polypropylene, and strip galvanized steel ensures high service life and resistance to environmental influences. The integrated multi-drive stud screw enables quick and secure installation, reducing installation time. The clamp is suitable for indoor and outdoor use, provided environmental conditions meet material requirements.
