Coming in at a hefty 120 grams, the Rega Heavy Tungsten Counterweight makes installing heavy cartridges on your RB-300 or higher tonearm a breeze. Substantially heavier than the stock counterweights, we have yet to find a cartridge the Heavy Tungsten Counterweight can't tame.

NOTE: This counterweight is not compatible with Rega arms that use screw-on style counterweights.
