Domes
Tip: It may be easier to mark hanger locations on a tape measure or a long stick and use this as a template
against the ceiling. If there are many obstructions, it may be easier to mark the locations on strips of tape along
the floor
(Figure 4), then use a laser to project the points to the ceiling.
Tip: Extra hanger holes are provided to help work around obstructions; however, the space between any two
hanger wires must not exceed 2 (every fourth hole).
Eight rows of hanger wires radiate from the center of the dome. As these rows diverge by more than 4,
additional rows of hanger wires need to be inserted between them
(Figure 4) .
