Abstract
Abstract An apparatus for supporting an edge-finishing strip along an edge of a partition-forming sheet of wallboard. A plurality of clips grip the wallboard along the edge in spaced relation to each other, the clips being supported on the wallboard without fasteners. An elongated finishing strip has a trim member for obscuring the edge and a flange insertable between the clips and the wallboards for supporting the trim member in obscuring relation to the edge. The clips may be provided with additional portions engageable with the finishing strip to enhance the support of the trim along the edge.
