Rega Tonearm Counterweight for RB100, RB202, RB220, RB250, RB251

Genuine new and original Rega counterweight for RB100, RB202, RB220, RB250 and RB251 tonearms, as well as many Rega OEM tonearms sold to other manufacturers (Moth, NAD etc).

This fits all Rega arms that have a coarse spiral 'cork screw' shaped tonearm stud (please see close up picture). Please note that the allen key on this weight should not be touched, this weight simply pushes on to the stub and after statically balancing the arm each half rotation forwards adds 1 gramme of tracking force. This counterweight is made from Mild Steel and weighs approximately 130 grammes.
