Just what is the jack chain supporting? Isn't the lower end fastened to the floor?Adding a new power pole to an office. There are 3 already there. They are screwed to the cieling grid with the usual provided trim plate,There is also 2 jack chains per pole(one on each side)over the ceiling,The chain goes up to the roof beams. are these supported OK?
It may just be resting on the floor, or attached to a modular furniture system.
If the whole suspended ceiling grid falls it might tip over if not independently supported.
