I've been given the window basket in the second image for my balcony, but the brackets the same company sells as extortionate! 😔
The dimensions of the ones listed are;
Minimum 2mm Thick Steel
150mm Long with 2 pre drilled holes on the rear piece which is drilled to wall
130mm depth / base which is where the planter sits.
40mm fold at the front to secure the planter in place.
Anything that would do the same job that I could attach to my balcony would be so welcomed!
Thanks
Hopeful Hannah
