If your door has been supplied with an optional Full or Half box assembled your overall size is pre-set.
Put cardboard protection down first. Place box on the floor against the opening where the door is to be
fitted, ensure overlap is equal on each side and mark a plumb line ‘A’ up each wall at the outside edge of
the box.
This is your outside edge of guide mark.
