Abstract
A utility duct for elongated utility members is mountable on a wall structure and includes a retaining strip disposed on the wall structure and a capping member. Upper and lower connectors connect the capping member to the retaining strip to thereby form an internal duct passage for the utility members. The retaining strip has a plurality of supporting walls which together with the retaining strip form gutter-shaped channels for supporting the utility members. At least one of the supporting walls has an outer end formed as a seat which seats against the capping member when the capping member is mounted on the retaining strip by the upper and lower connectors.
