Measure from wall to wall (or skirting board to skirting board if you chose not to remove it). Cut the plinth to size, minus 2mm. Drill holes (5mm diameter) centrally in width of the liners approx 150mm from each end and space out the remaining screws evenly at a maximum of 500mm centres.
Place the plinth in position. It is essential for the proper running of the doors that the bottom track is level, so check using a spirit level to ensure this. When you are satisfied, fix the plinth to the floor and wall with suitable countersunk screws ensuring the head of screw finishes flush with the face of the plinth.
