The Flick Lift System(TM) responds to a single upward motion and carries the canopy into place on its own. Sunbrella(R) solution-dyed acrylic canopy in your choice of color or pattern, on an anodized aluminum frame built for ongoing outdoor exposure. Available in 8' and 10' sizes. Also available in round . Base sold separately.
