Juices packaged with Bag-In-Box are supposed to be stored with a slightly liftet rear side, to avoid air getting into the box spoiling hte contents.
Put the box on this handy support to easily avoid that.
Fits 5l Bag-In-Boxes.
10 l fit onto it, but they have pretty much overhang to the reare. For smaller Boxes it's too wide, but it will work.
There are two versions - if you got your Bag-In-Box in a shelf above shoulder height i recommend the “Closed” version (dark green), to avoid pushing the box over the holder when pulling the whole assembly out. Otherwise there is no need to spend material for closing that hole, so choose the “Open” version (olive)
