This product gives a breakthrough for collapsible umbrellas. A cord runs through the hollow frame, acting as the opening and closing device. By pulling the cord, the arms are pulled outward at the top, collapsing the umbrella. A double canopy allows air to leave through the top, preventing updraft from breaking the frame. It helps to provide stability and durability, increasing the life of the umbrella.
