Today I picked up and fitted the roller door for the appliance cabinet. It is a bit of a low point in the whole design, since it is actually the only part not fire retardant and not rot proof. It is MDF based and pretty heavy and bulky for what it is, but I did not find an alternative for a custom made roller door. We will see how it stands up to the use especially in tropical, humid climates.
Was easy to mount, fits perfectly, slides easy with tensioned spring and blends in perfectly with the anodised alu extrusion I use as trim. I will eventually fit separation walls inside when we have finally decided what goes where in the kitchen.
