  • The Jackson Bros ball drive dial has a 4" diameter reversible aluminium scale that is printed 0-100 over 180˚ on one side. The other side is left blank for the customer to engrave.

    The brass friction drive mechanism, which has a reduction ratio of about 6:1, is mainly housed inside the plastic knob. The whole assembly is mounted on the 1/4" shaft of the component and only one other hole (for the anchor pin) is required in the panel. There is sufficient clearance between the drive mechanism and the panel for a component fixing nut or screws.
