A ceiling mount support tool for temporarily mounting an electrical device, such as a ceiling fan to a ceiling bracket. The ceiling mount support tool has a shaft, a ball joint at the proximal end of the shaft, and a socket at the distal end of the shaft. The ceiling mount support tool is mounted to a ceiling flange, and the ceiling fan is mounted to the ceiling mount support tool. Thereafter, electrical wires can be connected, and then the ceiling fan and the ceiling mount support tool can be removed. The ceiling fan with the wires connected can then be mounted to the ceiling bracket.
