Cables descending device for electric installation, has curved part broader than flat part that is formed on opposite sides of curved part, and partial openings respectively arranged under plane defined by flat part

摘要

The device has a body (1) provided with constant thickness, having a flat part (2) extending to a level of a front end in a curved descending part (3). A fixation unit of the body fixes the body on a longitudinal wire and a transverse wire of a cable trough. The curved part is broader than the flat part that is formed on opposite sides (31) of the curved part. Partial openings (7) are respectively arranged under a plane defined by the flat part, where the partial openings are arranged in a symmetrical form.
