Adjustable width: thanks to the holder, you can easily place the flower boxes on both metal and wooden railings with rungs. The adjustable hooks adapt to any railing width from 1 to 9.5 cm. No drilling required: thanks to our holder, you save space on the balcony, because you can hang the flower boxes firmly on the railing without having to drill. Durable plastic – the balcony box holders are made from a robust plastic. The hooks are resistant to all weather conditions as well as UV radiation and do not fade in the sun. Robust balcony box holder: the well-attached box does not wobble, does not slip and will not fall off. The attached box is kept stable even in strong winds. Range of variations: in our offer there are two or three brackets for the secure hanging of the box on the railing. Different colours are available, so you can easily adapt them to the boxes.
