The industry standard has been raised by this extra-large 11 foot California Market Umbrella. This umbrella offers all the features a residential owner demands, along with advances in design often reserved for commercial use. The tough aluminum pole is matched by the innovative use of a ½ inch diameter premium fiberglass rib system, which adds flexibility and longevity under windy conditions. In this extra-large canopy, by using thicker and more resilient fiberglass, the advanced collar tilt design separates tilt position control from the user-friendly crank to open features. Owners have a complete range of tilt positions at their fingertips and a resilient, easy to use, umbrella frame that will bring years of shade enjoyment.
