How to Measure

We need the overall size of the door to be installed. Using a Tape carefully measure:

Door Height:Measure the height of the opening in two places.

Door Width:Measure the width in three places. 150mm from the top and bottom, and the opening at the centre.

We need to check if the door frame is square. Measure the diagonals with a tape measure as illustrated, and check to see if the two distances match. If they are equal, the door frame is square. If the frame is out of square, you may require a slightly larger door and trim to size. A trimming allowance of up to 3mm is allowed on all doors. Approximately 3mm clearance is required at the top and sides of the door and 5mm at the bottom (above the floor covering)
