A hoist for a garage door opener has three main components. A base which is sufficiently wide to provide stability and has wheels to facilitate placement of the device, an extensible shaft extending from said base, and a self leveling workpiece holder for holding said garage door opener in position for installation. Installation of the garage door opener is then accomplished by placing the motor and motor housing of the opener on the workpiece holder and positioning the free end of the drive shaft of the opener above the door. Then the extensible shaft of the device is raised until the opener housing is properly positioned for installation on the garage ceiling. Once the opener housing is securely attached to the ceiling the device may be collapsed and transported or stored as required.
