Telescopic doorset
The Portman telescopic doorset effectively allows two door leaves to be concealed in one wall (on the same side) and almost a double span to be traversed.
The door leaves are linked via a toothed belt and pulley system so as the user extracts the first door leaf the second is gently brought along with it and conversely opposite happens when the doors are concealed back within the wall.
The doorset is non handed and timber framing is supplied offset as only one leaf makes contact with the closing jamb.
