ABSTRACT:
The present invention provides an adjustable, portable railing system for use with raised platforms or the like. The railing system broadly includes a plurality of generally horizontal rails and generally vertical uprights for supporting the rails. The uprights include a standard carrying at least one railing bracket, a platform clamp mechanism and a platform clamp operator. The elongated post-like standard has an upper crown end, a lower base end and a generally central longitudinal axis. The crown end supports the railing bracket and the base end is associated with the platform clamp mechanism. The platform clamp operator has a generally central longitudinal axis that is closely adjacent and substantially parallel to the axis of the standard.
