This California Umbrella BA 908 model is an exciting cantilever umbrella that opens up tremendous possibilities for any space. The large 9 foot canopy tilts and turns 360 degrees to offer the most dramatic shade potential. With a strong 2 inch diameter aluminum pole, stainless steel crank system and a standard base with pre-drilled ground anchor holes; this tough design will stand up to the rigors of use. It is recommended to use at least 100 lbs. of weight on the base if the frame is not anchored to the ground.
