ABSTRACT:
In an adjustable corner post for suspension scaffolding an outer tube is concentric to an elongated member such as a wire rope or rod and has an internal thread in a nut at one end. A tubular adjusting screw having an external thread is concentric to the elongated member and screws into the thread of the outer tube for reacting directly or indirectly with the elongated member so the outer tube rises and lowers when the screw is rotated in opposite directions. A platform supporting structure is supported on the adjustable posts and is leveled by selective rotation of the screws. A method of assembling suspension scaffolding using the adjustable posts is described.
