1mm thickness main rotor grip spacers for 5mm drag bolt.

The outside diameter is 29mm, slightly wider than the rotor head. When installing the rotor on the rotor head, this product makes it easy to align the holes on the grip, spacer and the rotor to pass through the drag bolt.

Using duracon resin as the material effectively reduces the slip vibration in the drag direction.

Also, these spacers are hard to scratch even if pressed against the grip.
