ABSTRACT:
The invention concerns a cable block, especially a lower block for cable controls, with at least one cable roller enclosed by a shrouding cover with entry and exit openings for a carrying cable, wherein a cover element is inserted in the entry and exit opening, having an opening for the carrying cable. The opening in the cover element is smaller than the entry and exit opening in the shrouding cover. In order to create a cable block, especially for a cable actuator, with improved protection against accidents, it is proposed that the entry and exit opening be slot-like and the cover element can be shifted in the entry and exit opening.
