Description

These circular back rings will fit the following chastity devices:

Steel JTS S601 Steel JTS S602 Steel JTS S603
Steel JTS S604 Steel JTS S605 Steel JTS S606
Steel JTS S607 Steel JTS S608 Steel JTS S609
Steel JTS S610 Steel JTS S611 Steel JTS S612

These are the only cages that these ring types will fit onto, so please check that you’re picking the right ring choice before you place your order.

For many years we've sold many, many cages that use our barrel lock and keys set to keep the cage locked. Models such as the S77 and the much smaller S83 but both of these designs have the top of the brass lock protruding slightly out the top of the ring. For some cage wearers that is an issue and we've listened to your feedback.

So, with our new range of S600 cages, we've hidden the lock away for you. It's now fully enclosed. Out of sight, out of mind. All you'll see now when you look down is a shiny polished steel cover over the lock. After thoroughly testing them we can confirm that it's added a new level of control and an extra layer to our chastity dynamic. We hope that you'll love it as much as we do.

Don’t know how to measure your back ring size? Don’t worry, we’ve got you covered. We’ve written the most complete measurement guide available, which you can use to measure not only your base ring size but your cage size too. Read our guide here before you order.
