    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 is coupled to the first pole and is slidably positioned into a protruded position for engaging into the plurality of apertures of the second pole for terminating displacement of the first pole relative to the second pole. The pin is slidably positioned into a retracted position for disengaging with 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 end of the second pole.

    Abstract: An extension tool is disclosed comprising a first pole and a second pole. The second pole is partially disposed in the first pole for defining a variable overall tool length. A slide controller includes a lower clamp and an upper clamp. The first pole is disposed in the lower clamp. A first clamp compressor applies a compressive force to the lower clamp for defining a lower clamp lock and coupes the slide controller with the first pole. A second clamp compressor applies a compressive force to the upper clamp for defining an upper clamp lock and prevents slidable displacement of the second pole relative to the first pole. The second clamp compressor applies a non-compressive force to the upper clamp for defining an upper slide guide. The upper slide guide facilitates the slidable displacement of the second pole relative to the first pole.

    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.
