Description
The Blue Line Prisoner Cock Cage is a black ABS plastic chastity device for male chastity, orgasm denial and consensual keyholder control. Available in two sizes with different cage designs, it restricts erections and limits direct access to the penis once locked. The base ring sits behind the testicles, securing the cage in place.
The 2" model has a short, enclosed shape with oval ventilation openings. It covers more of the shaft, limiting access to the penis and creating a closer sense of confinement. The 4" model has a longer, open-bar design that leaves more skin exposed. Its widely spaced bars provide greater airflow and allow the keyholder to see more of the penis.
Both cages have curved profiles, smooth plastic surfaces and a locking point above the base ring. ABS plastic is hard and does not stretch to accommodate an erection. The penis is restricted by the available space inside the cage, making the correct length and ring fit particularly important.
The Prisoner Cock Cage is suited to chastity arrangements involving a partner who controls release. The locking mechanism prevents ordinary removal until unlocked. The enclosed model provides greater coverage for men interested in more complete restraint. The open-bar model leaves the shaft more accessible for inspection and teasing.
Choosing the right fit: Measure your fully flaccid penis and the circumference around the base of your penis and behind your testicles. The shaft should fit inside the cage at rest with no constant compression. The base ring must remain secure without pinching or restricting circulation. A shorter cage can feel more restrictive, but excessive pressure is not a sign of a better fit.
Size guide:
2": Short, enclosed cage with oval ventilation openings. The advertised 2" length is a nominal size and should not be assumed to be the exact usable internal length. Greater shaft coverage limits direct access to the penis.
4": Longer, open-bar cage. Listed cage length: 4"; cage diameter: 1.5"; base-ring diameter: 1.75". The open design exposes more of the shaft and provides greater airflow. The stated cage length is not a confirmed internal measurement.
Begin with short periods to assess the fit and check the skin regularly. Remove the cage immediately if you notice pain, swelling, numbness or changes in skin colour.
