TUUCI's most durable and wind-resistant design is the F-1 MAX. Thanks to the tension-resistant stainless steel reinforcement cables and Armor-Wall Aluminum construction, this umbrella can withstand winds of over 100 km/h. The F-1 MAX is mounted directly into the ground with reinforced concrete and steel anchors to withstand all the elements nature can throw at it. The ground socket is sold separately. The umbrella comes with a crank system.
