The disclosure relates to a retractable caster assembly for use on large safes weighing in the 1000 pound range and above. The caster assembly utilizes a plurality of retractable casters which can be lowered to permit moving a safe from one place to another. Once the safe has been moved to its desired location, the caster assembly is raised while the safe is simultaneously lowered to the building floor. The caster assembly eliminates the need for specialized equipment to move the safe. Once the safe is lowered and the caster assembly is retracted, it is totally hidden from view, thus preventing the unauthorized movement of the safe since access to the caster assembly is only available when the safe door is open.
