2-6. Installation of Half Ball
Locations with suspended top suit the constant speed ball with in-ceiling
installation style, which appears to be a hemisphere, having an elegant look and good
concealment. The hemisphere style installation applies to solid locations of the ceiling.
First, select the desired location, mark the outline of the upper housing on the ceiling
with a pencil and make a corresponding-sized bore, then insert the upper housing into
the ceiling, and press the spring pinning boards against the edge of the ceiling opening.
After that, tighten the screw adjusting the spring pinning boards, and lock the upper
housing in the ceiling tightly. For the sake of better safety, please use a metal wire
rope to connect the top of the upper housing to a reinforced structure of the ceiling.
(The wire rope is required to bear at least 5 times the weight of the constant speed
ball.) (See Picture 9)
