ABSTRACT:
A vertical member support stand is described which includes a body with a generally tubular vertical member receiving cavity. The cavity has a bottom, a top opening, and circumferential sidewalls. At least three upper pressure members are substantially equally spaced around the circumferential sidewalls of the vertical member receiving cavity adjacent the top opening. The pressure members are pivotally mounted whereby they are pivoted into engagement with a vertical member positioned in the vertical member receiving cavity. At least three lower pressure members are substantially equally spaced around the circumferential sidewalls of the vertical member receiving cavity adjacent the bottom. The pressure members are pivotally mounted whereby they are pivoted into engagement with a vertical member positioned in the vertical member receiving cavity. The pressure members are locked in a selected pivotal position such that they securely hold the vertical member.
