A sober balcony railing is transformed into a lushly blooming eye-catcher when a flower box is attached to it. Since the combination of container, soil and plants creates a considerable weight, the holder must be constructed in a correspondingly stable manner. These instructions explain how to build a metal balcony box bracket yourself.
Wooden balcony boxes can be screwed directly to wooden balcony railings
Material procurement and processing
Measure the thickness of your balcony border precisely in advance. To procure the right material, go to a hardware store or a locksmith you trust. There you can purchase 2 steel sheets with the following dimensions for each flower box (€16.99):
- Steel sheets: 100 cm long, 3 cm wide and 0.5 cm thick
In the metal shop, you have each sheet of steel bent into a U-shape. It is important to note that the short side should be about 20 cm long. The long sides of the steel sheets allow you to bid for another 'U', matching the bottom width to the width of the planter that will be placed here later.
The remaining steel sheets are shaped according to this scheme until you have 2 brackets available for each flower box. If it is a balcony box (€109.00) with a length of 100 cm or more, we recommend a third bracket for the middle.
Attach the bracket - this is how it works
You can now hang up the finished brackets on the balcony railing at home. Place the shaped metal sheets in such a way that they fix a balcony box on the right and left by a few centimeters. Please note that these brackets only prevent a flower box from falling off the railing to the ground. Therefore, do not place an empty plastic box in the brackets, as strong winds could literally knock it off its hinges.
tips
If you build a wooden flower box yourself, think about the right bracket during construction. Screw the curved brackets to the right and left and in the middle of the balcony box, with the help of which you can hang the planter securely on the railing.
