Cabling canal with anti-slip function

摘要

The duct has two side walls transformed by slots (16) running perpendicularly to a base of a U-shaped lower part to tongues (12). Cover holding profiles (14) are provided at free ends of the tongues. A cover (20) is provided for attachment on the lower part with laterally formed form-profiles (22), which cooperate with the cover holding profiles of the lower part. Knobs (24) are formed at an interior side of the cover holding profiles. The knobs are gripped into the slots of the side walls of the lower part formed by the tongues.
