Abstract
A modular portable handrail system employs cantilever arm/counter-weight anchor assemblies. Bases attach to opposing ends of the cantilever arms. A pail-like receptacle is receivable on one of the bases and interlockable with the base. The receptacle is filled with water, sand or other material to provide the counter-weight mass.
