Abstract
A retractable arm device, system, and method with a locking mechanism for preventing items placed in a device or receptacle from getting stuck, damaged, or torn. The retractable arm includes an inner tube, a pawl, and an outer tube surrounding the inner tube. The inner tube slides within the outer tube and the pawl preventing the retractable arm from moving into an extended position under particular conditions. The retractable arm may be placed in a receptacle for items to prevent the door from being reopened before the door is fully closed.
