AGO/40 Dunlop Optical Guages
The Dunlop AG0/40 optical alignment gauges are the industries standard tracking gauges. This basic design has been in use since the mid-sixties with almost every garage and tyre shop having a set. They are the quickest method of accurately checking front and rear toe angles (tracking).
The gauges measure in fractions of a degree that can be converted to millimetres or inches using the calculator dial.
Calibration of this unit is very simple and any user can do it in a matter of minutes.
