Abstract
A scaffolding structure is configured to provide dual walk-through areas with each walk-through area being at different elevations of a scaffolding section. Each section of the scaffolding structure includes two end frames with each end frame having a forward column, a center column, and a rearward column. The forward and center columns are connected by a walk board support and the center and rearward columns are connected by a work board support. The end frames are interconnected by a walk board joined at one end with the walk board support of one end frame and joined at the other end with the walk board support of the other end frame. A work board also interconnects the end frames in similar fashion with one end of the work board joined with the work board support of one end frame and the other end of the work board joined with the work board support of the other end frame. Cross-bracing of the end frames relative to each other and a handrail connected between the rearward columns of the end frames are employed as needed. Receptors in the ends of the forward, center, and rearward columns are configured to closely receive a stud to enable multi-level, vertical stacking of like scaffolding sections. Electrical outlets are provided at the center column of the end frames. An electrical conduit positioned within the center column provides electrical continuity between an electrical power source and the outlets. Jumpers are employed to establish continuity between adjacent vertical scaffolding sections. A substantially non-load bearing ladder may be attached to one or more of the end frames. A corner walk board and a corner work board are provided to achieve continuous scaffolding around comers of structures.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
