Pro-ject Anti-Skate Hoop
The Pro-Ject Anti-Skate Weight Support Hoop / Anti-Skate Arm is the metal rod, which is screwed into the base of most Pro-Ject tonearms. It comes out of the arm base at an angle, and is designed to allow the anti-skate weight (which is attached to the arm) to hang freely.
*Please Note: This item does not come with the screw to fix it in the arm base.
