The 3m Crank and Tilt Parasol can be used within your dining tables or as a free-standing parasol provided you use a weighted base (not included) to keep the parasol in place. This product features an easy-to-operate crank and tilt system which will help you to adjust the canopy position when required. The parasol is fully closed. We always recommend that the parasol remains closed when not in use and is always kept closed in extremely windy conditions. The Crank and Tilt parasols are made using a polyester fabric that has a weather-proof coating & UPF Sun protection Level 50.
