A device for measuring the thickness of a live contact wire, such as those used in overhead line equipment (OLE) for electric trains. The device 300 includes a first arm 304 having a first hook 302 for hooking the contact wire. A second hook 303 hooks over a catenary wire and is mounted on a second arm 305. A laser rangefinder 307 is mounted on the arm at a position of a known distance/displacement from the first hook 302. The laser rangefinder measures the distance from an object located at the first hook 302 to a second object located proximal to the second hook 303. The measured distance is used calculate the diameter of the contact wire from which the thickness is derived. The measured diameter may be compared to an expected value to calculate total wear of the wire. The second arm 305 may be slidably attached to the first arm 304. Preferably, the device is mounted 301 on an electrically insulated non-conductive pole to be held by an operator. Ideally, the device transmits the thickness measurements to a remote / portable electronic computing device 309 held by the operator.
