Abstract
An extension tool is disclosed and comprises a first pole and a second pole. The second pole is slidably received within the first pole. The second pole has a plurality of apertures. A pin lever is pivotably mounted relative to the first pole. A pin slidably engages within the pin lever. The pin lever is released for inserting the pin into the plurality of apertures of the second pole for terminating displacement of the first pole relative to the second pole. The pin lever is depressed for removing the pin from the plurality of apertures of the second pole for permitting displacement of the first pole relative to the second pole. A device, tool or support may be secured to the second ends of the second pole. In one embodiment, a claw is secured to the second end of the second pole for engaging either a knuckle coupler or a wheel brake of a railroad car.
