Abstract: A support work prop is described which has a main body section formed from interconnected aligned soldiers. Head and base sections are provided for interconnecting the upper and lower ends of the soldiers which may themselves be connected to either screws or jacking members, header beams or bearing plates. The prop can be readily disassembled to allow the soldiers to be employed separately so that the arrangement allows them to have a dual purpose.
