Our portable umbrella is rated and warranted for windy environments up to 35mph, one of the strongest ratings available. No permitting, installation, or site construction is required! The umbrellas will leave the factory 90% assembled. All the end user needs to do is place the weighted plates on the base, attach the top frame, and put the fabric on. The intuitive dual-drive system opens and retracts the umbrella in less than a minute!
