B Cable clamp for fastening to C profile rails

The B cable clamp with full-surface pressure trough can guide cables with a maximum diameter of 70 mm. It is suitable for attachment to C profile rails with a slot width of 11-12 mm. On request, a GW counter trough can be fitted for improved cable support. Different materials and surfaces ensure that the corresponding requirements for different areas of application are fulfilled.

The article is also available with lock nuts. This prevents the clamp from unintentionally coming loose. Lock nuts must be specified separately when ordering.
