Claim 11

In combination: a gypsum board panel; and a plurality of suspension assemblies attached to the panel at its rear face for suspending the panel from a channel member of a support structure, each said suspension assembly comprising; a plate having upper and lower portions, means defining a transverse line of weakness between the upper and lower portions so that the plate preferentially bends along the line, and a plurality of panel-piercing members projecting outwardly from one face of the upper and lower portions of the plate and extending into the panel, without protruding through the front face thereof, to secure the plate to the panel, and a suspension clip, said clip having an upper portion attached to the plate above the line of weakness and said clip having a lower portion which overlies the lower portion of the plate, said lower clip portion defining a cam surface arranged to engage over a side leg of the channel member, whereby when the panel is suspended from the channel member, the load applied between the plate and the clip causes the plate to bend about the line of weakness in a sense to incline the panel piercing members of the lower plate portion in an upwards direction.
