slightly because of high temperature or humidity. For this
reason, before drilling the holes maintain the correct dimensions
between the markings.
(1) If the full-scale installation diagram is placed on the ceiling,
the locations of each suspension bolt can be chosen.
Take a pencil and mark the drill holes (Fig. 4-9).
