Abstract
An installation duct for utility lines, particularly for two-pipe installations, is formed by a retaining strip at the wall side and a capping attached thereto, and can be provided in the upper region with a feedthrough opening for vertical branch piping. In order to close off the installation duct in the region of the branch piping with little effort and to fashion it so that it can be made to fit different pipe diameters, the capping has, in the region of the feedthrough opening, a covering hood which can be made to fit different branch piping arrangements.
