The Wall Oven Microwave Open cabinet consists of 2 sections. The lower section has a coloured top and bottom with 2 whiteboard gables between. The gables are fixed to the top by cam joints to avoid any seen fixings in the open section. In addition to the coloured top of the oven frame there are 2 loose coloured panels that are fixed on site to form the microwave open section.
The over height is taken from the bottom of the oven frame to the top of the microwave open section.
As you can see the coloured back extends up behind any W/O Top cabinet but is not included in the overall height.
