Before fitting a drywall, I measured 12cm from the ceiling and fitted battens (wall studs) across the length of the room to support wall cabinets.
I didn't leave enough room - the wall cabinets are now too high.
Does anything exist such as a metal piece that will act as a lowering mechanism to keep the existing support at the 12cm but allow the cupboard to hang lower e.g. at 24cm from the ceiling. I'm imagining a piece of metal that hooks to both the wall fixture and the cupboard but I'm not sure if it exists.
The battens are 1.5 inches because I needed to bring it in front of some pipes.
Also open to other suggestions.
