ABSTRACT:
A universal, knob-dial control member for association with the control shaft of a cold control regulator wherein the knob member is uniquely configured so as to be adaptable to be used on a plurality of cold control regulators in and of itself or alternately, adapted to have the dial member disassociatible which accommodates still other cold control regulators. The provision of the knob-dial control member in kit form, having selectable knob members, provides a means whereby inventory is substantially reduced and a service man has the ability to service a large number of cold control regulators without the need of having a large number of specialty repair and replacement parts.
