Track joint for RETRÖ fitting set. It allows you to seamlessly connect / extend the track as you like and, for example, connect two sets of fittings. This method is used e.g. when the double doors of a large door opening are desired to run on the same track (bi-parting) and open completely out from the front of the door opening to the sides.
Such sliding doors bring spectacle, for example, in the living room as room dividers. Note! The door can also slide over the track joint if necessary.
