the combination of : a scaffold assembly comprising a vertical member ; a baseplate on the vertical member and having a downwardly facing surface ; and a foot having a top surface and a bottom surface spaced in an axial direction . the foot has an opening in the top surface and a recess extending axially from the opening toward the bottom surface . the recess accepts the baseplate with the baseplate in an operative position . the downwardly facing surface bears on the foot so as to cause a downward force produced by the vertical member to be applied to the foot and distributed by the foot through the bottom surface to an underlying support surface for the scaffold assembly . the bottom surface on the foot has a peripheral edge that bounds an area that is greater than an area bounded by a peripheral edge of the baseplate .
