ABSTRACT:
A resilient sheet metal runner for attaching wallboard to a supporting structure comprising a base attaching flange having a resilient web coextensive therewith and integral with a longitudinal edge thereof with a support portion integral with an opposite edge of the resilient web and a stop flange integral with the opposite edge of the support portion. The base flange is disposed in a first plane, the flexible web is disposed in a second plane at an obtuse angle to that of the base flange and with respect to a third plane represented by the support portion. The stop flange extends at an obtuse angle toward the first plane in a fourth plane which it occupies but is of less width than the resilient web so that it does not extend into the first plane. The resilient web is slotted for increased flexibility and the base attaching flange is provided with laterally offset fastener tabs to space the attaching flange from the supporting structure and thus obtain further improvement in the prevention of transmission of vibrations impinging on the wallboards mounted on the sheet metal runners.
