A knock-down swing stage base includes a pair of extruded aluminum beams with generally C-shaped cross-sections. The beams are oriented parallel to one another and joined by identical aluminium cross-members. Each cross-member is integrally extruded with paired ribs defining a set of screw receiving passages in a predetermined spacing arrangement. Sets of apertures are formed in the webs of the beams at regular intervals, each set observing the spacing arrangement characteristic of the set of screw-receiving passages. Each cross-member is located with its set of screw-receiving passages simultaneously registered with a set of aperture in one beam and a corresponding set in the other beam. Screws are used to releasably secured the cross-members to the beams. A combination of left-hand and right-hand screws are used to enhance resistance of the base to twisting. Brackets are shaped to receive and slide along an upper flange extruded with each beam. Each bracket carries an upwardly-directed length of pipe for receipt of a vertical post associated with an enclosing structure, such as a hand rail.
