The door is fixed to an opening mechanism that lets the door slide along the side of the cabinet when it is open. This makes it disappear so that it doesn't get in the way of people moving around the kitchen as well as making the entire contents of the cabinet readily available. It also conceals small household appliances and ovens from view.
If there are electrical appliances such as an oven installed inside a cabinet with pocket doors, for safety reasons it's advisable for these to be off when the cabinet is shut. In these cases we supply a device with a switch which interrupts the power supply to the oven, letting just enough electricity through to make the display work so that you don't have to reset it every time you shut the door.
