The doors (2) are removable and can be hung on the wall (3). The door holder (3) has a door catch device to serve as holder for the door. By removing and reversing the door the door can be brought out of the work area. The door panel has an opening (4) large enough to allow the door to fit over the door holder. The door catch device is divided to hold several door panels. The door panel can be designed so that it is guided round the carcase (1) and then brought with the ends into the catch device. The door holder can be eccentric and used for tensioning.
