Due to floor-to-ceiling windows, we lack a windowsill for all our plants. We had a marble slab cut for the radiator. But in order to provide sufficient convection, a certain distance between the radiator and the marble slab must be ensured.
It is an old cast iron radiator (ribbed radiator). Suitable for the space between individual ribs I have constructed screwable holders. These are firmly clamped by the screw connection and at the same time provide enough support surface for marble plate.
