A tool is provided for clamping, spreading and jacking activity and comprises rectangular, tubular extension bar members, which are used independently or are interconnected to establish a desired tool length. The extension bar members have a plurality of spaced positioning holes located at top bottom and sides along its length to provide length adjustments. Jaw members are selectively attached to the extension bar for force transmitting engagement with a structure or device. A power head having a tubular bar is provided with spaced shoulder members which provide support for a threaded actuator rod extending between them. A head jaw is disposed in moveable guided relation with the rectangular extension bar of the power head and is moved by a drive nut type actuator member which is in threaded relation with the threaded actuator rod and has driving engagement with the head jaw. The actuator member is selectively rotated on the threaded actuator rod by a ratcheting box end wrench for application of spreading or clamping force to the head jaw. Spreading, jacking or clamping activity is selected by selecting the position of the power head with respect to the tubular extension bar.
