A grasping member which may be operated from a distance to inflate it and thereby engage an object, such as a light bulb, in order to unscrew the bulb from its socket, is disclosed. The member is an inflatable chuck, which may be mounted on the end of a long pole. In one embodiment, the walls of the chuck form a pocket for a light bulb located in a high ceiling or other hard-to-reach place. When inflated, the walls of the chuck enfold and grasp the bulb to permit an operator holding the pole to turn it and unscrew the bulb. Another embodiment of the chuck is also disclosed in which the walls of the chuck expand outwardly instead of inwardly when the chuck is inflated.
