Abstract: A tool for use by truck operators includes an elongated member rigid throughout its length terminating at its rear end portion in a handle and terminating at its front end portion in a socket having a recess therein adapted to receive a load binder handle. A hook extends from the socket and is adapted to engage a fifth-wheel release mechanism handle. In use, the tool may serve as an extension of a load binder handle for facilitating the locking and release of a load binder for a vehicle, and it may also be used to conveniently engage with the hook thereon a fifth-wheel release mechanism handle which is normally not located in an accessible area of a trailer. The tool also serves the purpose of checking the tire pressure of the vehicle by enabling the operator to strike the tires with the socket end of the tool, whereby the operator can by observing the sound of the tool against the tire determine whether or not the tires are under inflated in a quick and easy manner.
