Two parallel side profile bars with cover retaining profiles are attached adjacent and/or at the u-shaped profile retainer, where the height of the side profiles corresponds to the thickness of a plank. A duct cover is locked for the completion of the electrical installation. The side profile bars are locked on a shank of the profile retainer. An independent claim is also included for an electrical installation system for the dry construction walls.</p> |
