A scaffold structure accessory is essentially comprised of a elongated, horizontal, laborer's alternate walkway and material support member having a clevis connector at its inboard end and a safety rail receptacle connector at its outboard end, a first vertical support member attached to the laborer's alternate walkway and material support member near its outboard end, a second vertical support member attached to the laborer's alternate walkway and material support member near its inboard end, and a connector on each vertical support member that co-operates with the scaffolding laborer's walkway and material support of a conventional prefabricated lift-type scaffolding module.
