ABSTRACT:
A unitary suspension clip for suspending gypsum board panels from the horizontal support member of a vertical support structure. The plate portion of the clip has panel-piercing members projecting rearwardly to affix the plate to the panel. A transverse line of weakness extends substantially across the width of the plate such that when the panel is suspended from the support member, the load applied between the support member and the plate causes the plate to bend therealong to prevent the pulling of the panel-piercing members out of the panel. A wing is formed along the edge of the plate and extends outwardly therefrom with a second line of weakness running in the same direction as the edge of the plate between the wing and the plate. The wing is bent at the second line of weakness upwardly from the surface of the gypsum board panel and is provided with bearing surface forming an angle relative to the plate which rests on the horizontal support member and causes the panel to be drawn into engagement with the vertical support structure. The bend of the wing and the spring tension of the material comprising the clip cooperate with the bearing surface to continually cam, or draw, the gypsum board panel against the vertical support structure.
