RAK/E is an adaptation roller shutter system characterised by the presence of an inspection hatch and an external plastering strip, allowing the box to be plastered from the outside and making it invisible. The system is designed to be built-in and is made entirely of aluminium, including the box, sides and guides. The lower part of the box is available in a variety of RAL colours, as well as veneer finishes in golden oak, walnut, dark oak and winchester.
