This stainless steel upgrade allows you to add some extra durable weight and security to your CB-X cage. Just slip the smooth metal onto your favorite CB6000, CB3000, or Curve chastity device and enjoy the feel of smooth metal against your rod. The numerous vents and extra wide end hole make it ideal for extended wear. The durable material is non-porous and resists rusting, so it is easy to clean and supremely secure. Works with standard 3 pin CB-X chastity cages. Just remove the existing cage and add in your new upgrade to enjoy the slick feel and incredible restriction of steel.
