An electrical box bar hanger includes an adjustable channel having a plurality of locking tabs at distal ends thereof and first and second end plates with each of the first and second end plates having a plurality of locking apertures thereon. The first and second end plates are integrally connected to each distal end of the adjustable channel. When each end plate is bent 90 degrees against each corresponding end of the adjustable channel, each of the plurality of locking apertures aligns with each corresponding locking tab, such that the plurality of locking tabs can be inserted into corresponding locking aperture to allow the first and second end plates to be perpendicular with the adjustable channel without the use of welding.

A device for securing an object to a ceiling includes a threaded rod, a bracket and a spring-loaded tab. The spring-loaded tab has a tab portion with an outer surface. The tab portion is rotatable about an axis perpendicular to the threaded rod. When the device is attached to the object and the object moves into an opening in the ceiling for installation to the ceiling, the tab portion is urged from an extended position to enable the object to pass through the opening. Subsequently, the tab portion returns to its extended position such that the object can be temporarily supported by the tab within the ceiling opening. The bracket is configured so that during a removal process, a portion of the bracket urges the tab portion inward from the extended position to enable the object to be removed from the ceiling opening.

Prefabricated wall panels simplify the constructive of dwelling units and other structures. The wall panels include an electrical junction that enables the wall panels to couple to other wall panels, allowing electricity to flow between panels. Each wall panel includes electrical conduit to allow for the flow of electricity within the wall panel. The electrical conduit is coupled to power outlets within the wall panels. In some embodiments, the wall panels additional include network line, enabling the flow of data between panels. The electrical conduit can transmit both power and data within the conduit. In such embodiments, a controller can decode the data signals from the power signals within the conduit. The wall panel can additionally include one or more components that can perform functions based on the data, or that can couple to devices or systems that can communicate via the conduit.

Systems and methods of the present disclosure enable modulate electronic communication between devices interior to and external to a structure via a ridge vent. A ridge vent covers a ridge slot in a roof of the structure to provide ventilation. A housing having a length, a width and a height that are sized to fit through a ridge slot of the roof includes a top a top portion proximal to the ridge vent, a bottom portion proximal to the interior of the structure and opposite to the top portion, and at least one wall extending between the top portion and the bottom portion. A securing mechanism is connected to the top portion of the housing to secure the housing within the ridge slot. An electronics bus is positioned within the housing and has an interface that enables operation of modular electronic devices that are removably positioned within the housing.
