CB-X Cockcage U Ring No. 4 is a replacement ring component for male chastity devices, engineered with a precise 41.275mm inner diameter for optimal fit and security. Manufactured from body-safe medical-grade plastic, it is compatible with all CB-X chastity device models. This ring maintains consistent pressure distribution and prevents skin irritation during extended wear periods, making it essential for users seeking reliable chastity system customization.
The CB-X Cockcage U Ring No. 4 functions as a precision-engineered base component that holds the chastity cage securely in place around the penis. The exact 41.275mm inner diameter creates consistent pressure distribution that prevents shifting or discomfort during wear. The specialized surface finish reduces friction points where the ring contacts skin, allowing for extended wear without irritation or pinching sensations.
Medical-grade plastic construction delivers durability that maintains its shape through regular use and cleaning cycles. The smooth, non-porous finish supports easy hygiene maintenance while resisting degradation from body heat and moisture. For those seeking additional sizing options or exploring different chastity configurations, our chastity wear features collection offers comprehensive alternatives.

Combining the CB-X Cockcage U Ring No. 4 with a secure locking mechanism allows for uninterrupted wear during daily activities, sleep, and intimate situations. Many users pair this ring with integrated lock cock cages to create a complete chastity system that balances security with comfort. Wearing multiple sessions helps identify whether the size remains optimal or whether alternative sizes in the CB-X range better suit your anatomy.
After each wear session, clean the U Ring with warm water and mild soap, paying particular attention to the interior surface where skin contact occurs. Rinse thoroughly and pat dry with a clean cloth before storage or reattachment. Store the ring in a cool, dry location away from direct sunlight to prevent material degradation. Do not use harsh chemicals, bleach, or abrasive scrubbers, as these can damage the friction-reducing surface finish.
Medical-grade plastic construction ensures the CB-X Cockcage U Ring No. 4 meets body-safe standards for extended intimate wear. The non-porous material resists bacterial growth and maintains hygiene through regular cleaning. The smooth surface prevents skin irritation even during prolonged contact, while the material's durability ensures it maintains its shape and structural integrity through years of repeated use and cleaning cycles.
This replacement ring suits anyone currently using CB-X chastity devices who needs a replacement component or wishes to adjust their fit. It appeals to those seeking the precision engineering and compatibility that CB-X is recognized for. The No. 4 size represents a balanced middle option in the sizing range, making it appropriate for many users regardless of experience level with chastity play. Those exploring extended wear or couples incorporating chastity into their dynamic will find this ring essential for maintaining system security and wearer comfort.
For people who have experienced discomfort from rings that shift, pinch, or create uneven pressure distribution, the precision-engineered 41.275mm diameter transforms what extended chastity wear feels like. When a ring is too loose, the cage rotates and creates friction points that become painful during normal movement. When too tight, circulation becomes restricted and skin develops pressure marks. The CB-X Cockcage U Ring No. 4 eliminates this guesswork through exact dimensional specification that accommodates the anatomical variation many users experience. For those frustrated by generic sizing that forces compromises between security and comfort, knowing that this component was engineered to precise tolerances means the difference between reluctant wear and sustainable practice. Upgrading to an authentic CB-X ring from the manufacturer signals commitment to both safety and the integrity of your chastity system.
Our independent testers evaluated the CB-X Cockcage U Ring No. 4 for dimensional accuracy, material durability, and comfort during extended wear sessions. The ring maintained its specified 41.275mm diameter throughout testing and demonstrated consistent pressure distribution across the contact surface without creating pressure points or circulation restriction.
Testers reported that the friction-reducing finish significantly reduced skin irritation compared to standard plastic rings, and the smooth surface simplified cleaning and hygiene maintenance. The material showed no degradation after repeated cleaning cycles or exposure to body heat and moisture. Individual results may vary based on anatomy, sensitivity, and usage.
