In some buildings, there is no room for rails, door panels or an engine. Parts of a service door may also get in the way of an installation or the space may be very humid or dirty. Think, for example, of car washes or spray booths. In such cases, external mounting of the Compact folding door offers a solution. The entire door is then mounted on the outside of the room. The door folds up and is neatly protected and finished by a protective cover. This can be powder-coated in any colour to match the rest of your building.
