HOW ARE HANGING LIGHT FIXTURES INSTALLED WITH THE BOX BEAM COFFERED CEILING SYSTEM?
All hanging light fixtures (i.e. chandeliers, ceiling surface mounted lighting) use a hollow threaded rod and/or machine screws for installation of the fixture to the electrical box so you would install the electrical box as you normally would. Then, depending on how much deflection there is in the ceiling and how much you need to adjust the Box Beam System Coffer Modules to overcome that deflection, will result in the use of a longer threaded rod and/or machine screws to accommodate the difference.
