The ‘Twin Cage with Sound’ offers highly focused e-stim via a 6.35mm sound with 40 mm depth guard, the conductive cage, and the polished aluminium base ring. Adjustable 'telescopic' length to optimise sensation. 

Sizing:

Available with a 40mm or 50mm internal diameter polished aluminium lower section.  6.35mm (1/4”) sound.  The design allows the distance from the base to the cage to be changed by adding or removing O-rings from the lower section.  Additionally the asymmetric placing of the cage in the upper section means that by revolving the upper section lengthways the distance from cage to base changes.  The combination of the two adjustments allows excellent length optimisation. 

 E-stim

The cage itself is bi polar so a common setup would be a cable with 2 x 4mm banana jacks to connect the cage and a second cable with 2 x 4mm banana jacks to connect the sound and aluminium base section. Other connection options could be cage to sound and cage to aluminium base.  Or a TriPhase cable connection.  There are lots of alternative connections to try.
