Rail stanchion for concrete slab walls

A railing mounting device for mounting at least one flexible railing to a concrete wall panel having a thickness, comprising a stanchion and an anchor insert adapted for mounting into a concrete wall panel wherein said stanchion is releasably mountable to said anchor insert, wherein said stanchion is elongate and extends longitudinally between opposite first and second ends, said second end have a mounting member mounted thereto so as to rigidly extend therefrom for sliding snug releasably securable mating engagement in a corresponding cavity in said anchor insert when the anchor insert is rigidly mounted into the concrete wall panel, said mounting member lying generally in a first plane containing said first and second ends, said first end laterally offset by substantially the thickness of the concrete wall panel in said first plane relative to said second end so as to extend over said mounting member in said first plane, said stanchion having a rail mount towards said first end so as to releasably mount rails to said stanchion offset relative to said second end over the concrete wall panel when mounted thereto.
