Abstract: A resilient channel for joining a board to a support such as a stud, joist or truss in building construction, has a mounting flange and a face flange joined by a web. The mounting flange has a first foot and a second foot disposed at ends of the flange, the first foot bent back toward the support to be disposed between the mounting flange and the support, the second foot bent toward the support, such that the first foot and second foot are disposed to bridge the mounting flange over the support to define a gap between at least a portion of the mounting flange and the support. The face flange has a first bend and a second bend disposed at ends of the flange, and corrugations between the first bend and the second bend.
