    Abstract: An electrical device hanger is shown and described. The electrical device hanger can be used to suspend electrical devices at a user selected height and location so that conduit and electrical power can be run from another location to the device. This hanger is especially useful in open ceilings and reconstruction ceilings in commercial buildings. The hanger can be attached to the ceiling with a pair of threaded rods, a single threaded rod or s-hooks and jack chains. The hanger has clearance holes in the top and threaded holes in the bottom. The threaded rod passes through the clearance holes in the top and can be secured in the threaded holes in the bottom alone or can also be threaded to the device suspended. The device suspended from the hanger can also be affixed to the bottom of the hanger with fasteners in the threaded holes in the bottom. Alternatively, holes are provided in the top of the device hanger to utilize s-hooks and jack chain to attach the device hanger and the device to the ceiling.
