The balcony umbrella holder clamp is the ideal solution when the limited space of your balcony does not allow for a traditional umbrella stand and your balcony is surrounded by a wall railing. You simply stretch the umbrella holder over the wall railing. With the integrated clamp, the balcony holder gets a stable grip. You then insert the umbrella pole into the holder's tube and secure it with the tightening screw. This way, your umbrella reliably shades a large area of your balcony, providing you with a pleasantly shaded spot. Since you can easily adjust the umbrella holder with just a few movements, you have the option to change the position of the umbrella at any time, allowing you to follow the sun's path. Suitable for umbrellas with a pole diameter of 16 mm to 35 mm and for balcony railings with a thickness between 7.5 cm and 22.5 cm.
