The tower has an adjustable base secured to the lower end thereof and a platform selectively vertically mounted thereon. A winch means is operatively connected to the platform and the upper end of the tower for selectively moving the platform between the upper and lower ends of the tower. An elongated angle member is secured to the platform and has a plurality of spaced apart brackets secured thereto. The brackets are adapted to detachably receive one end of a cable tightener. The other end of the cable tightener is connected to a canvas loop secured to the periphery of the canopy. A plurality of individual towers may be tied together by braces or the like so that the towers may support a large canopy.
