A customer of mine was worried about this as a problem because his existing cheap parasols kept breaking because of this. Here is my answer:

"Further to our conversation this morning, here are some answers for you:

• I have spoken to the UK importers. They agree with me that here is no danger of the struts being tangled on the Tradewinds parasols when they are being put up. The frame and strut thickness and strength means that this does not happen.
• Here is a copy of the instructions for opening and closing the parasol for you to check that you are happy with it:
  • Opening the parasol - once you parasol is placed in its base it is ready to open. Undo the tie that holds the canopy and release the ribs of the umbrella so that each of the struts moves freely. Gently pull the ribs outwards till the hub starts to move on the pole. DO NOT APPLY FORCE. Pull on the pulley cord to slowly raise the hub upwards. Continue this till the fabric is taught and at least one of the holes on the main pole is visible below the hub.Insert the pin through the hole so that the sides of the hub will rest equally on either end of the pin.
  • Closing the parasol - with the pulley system, raise the hub slightly to take the pressure off the holding pin. Remove the pin from the pole and gently lower the hub, ensuring that there are no obstructions. Allow the parasol to close slowly. Do not let the cord run through your hands as this may cause friction burns. Ensure that the canopy fabric is not caught between the struts and then wrap the canvas round the parasol and secure using the tie."
