Replace the base ring on a compatible metal chastity cage, or try a different size or profile without buying another complete cage set. These polished 304 stainless steel replacement rings are designed for selected metal cages with a matching integrated sliding-lock connection.
Choose from four designs: Circular K-01, Curved K-02, Circular with Strap Loops K-03, and Curved with Strap Loops & Hook K-04. Each style is available in 40 mm, 45 mm, 50 mm and 55 mm sizes.
One base ring per order. Select your ring style and size. The cage, waist strap, lock and keys are not included. Photos with straps show how the attachment points can be used.
Choose Your Base Ring Style
-
Circular - K-01: A round ring with a polished, rounded band and no side strap loops.
-
Curved - K-02: A contoured alternative to the circular profile, with a visible curve through the ring body and no side strap loops.
-
Circular with Strap Loops - K-03: A round ring with two side loops for a compatible support strap.
-
Curved with Strap Loops & Hook - K-04: A curved ring with two side loops and a lower hook with a rounded end.
The polished surface and rounded ring edges give each design a smooth finish. The open ring structure leaves the surface accessible for cleaning. K-03 and K-04 add dedicated attachment points when you want to use a compatible support strap.
Sizes and Approximate Ring Weights
Each style is available in 40 mm, 45 mm, 50 mm and 55 mm sizes. The K-01 and K-02 diagrams show the opening measured across the inside of the ring. Compare the profile as well as the size: a curved ring has a different shape from a circular ring.

Compatibility with Metal Chastity Cages
These rings fit selected metal chastity cage models with the matching integrated sliding-lock connection. Compatibility depends on the cage-to-ring attachment, not just the ring opening size. They are not universal replacements and are not suitable for cages that use a hex-key screw locking system.
Compatible models include the JTS S239 Flat Stainless Steel Chastity Cage, which accepts all four ring styles. Other compatible models are also supported; if your cage model is not listed, contact us with its model name or your TemptCove order number and a clear photo of the connection before ordering.
Our chastity cage size guide explains how to compare base-ring measurements.
Care
Remove the ring before cleaning. Wash it with warm water and mild soap, rinse thoroughly, and dry it before storage. Clean and maintain any separate strap or lock according to its own care instructions.
Base Ring Questions
Can I buy a ring without buying another complete cage?
Yes. You can order one replacement base ring in your preferred size and style for a compatible metal chastity cage. Check the cage connection as well as the ring size when choosing a replacement.
What is the difference between Circular and Curved?
The Circular styles have a round profile. The Curved styles have a contoured ring body. K-03 and K-04 also have side strap loops, and K-04 adds a lower hook.
Are all four sizes included?
No. Each order includes one ring in the selected style and size. Size-comparison images show the available choices.
