Abstract: A system for assembling and installing a modular spiral chute includes a base support assembly having a plurality of rear rollers and a slot, where the slot is orientated in the base support assembly to receive a vertically positioned stanchion of the modular spiral chute. The system also includes a removable roller clamp having a front roller and configured to be inserted into the slot to form an aperture in the base support assembly to encircle the stanchion so that when the roller clamp is inserted into the slot the stanchion is rotatably secured vertically within the base support assembly between the plurality of rear rollers and the front roller. In addition, the system includes a caster mounted plate positioned on top of the base support assembly and configured to increase stability of the stanchion when secured within the base support assembly.
