Abstract: A scaffold system having modular components including interconnectable side walls or side trusses having extruded upper and lower truss members, decks and various section connectors which are interchangeable simplifying transportation, minimizing storage and reducing inventory requirements. Single person set-up and take-down is provided in a modular scaffolding system allowing assembly of a vast array of configurations that accommodate various architectural shapes. Drop-in assembly of aluminum side trusses of modular scaffold sections with steel modular scaffold section connectors provides strong construction. Spring loaded latched are used to maintain decks in place at modular scaffold section connectors.
