Description
The Blue Line Prisoner Cock Cage in Black is a stainless steel chastity device for male chastity, orgasm denial and consensual keyholder control. Its curved metal enclosure surrounds the penis, restricting erections and limiting direct access to the shaft once locked. The 4.75" cage length and 1.6" internal diameter are important measurements when assessing fit, particularly for men who prefer a longer metal enclosure.
Stainless steel does not stretch when an erection develops, so the shaft is restrained by the space inside the cage. Open sections provide airflow and leave areas of skin accessible for inspection. The metal also has more weight than plastic or silicone alternatives, which may appeal to men who prefer a heavier chastity device.
Assorted fitting rings help accommodate different measurements around the penis and behind the testicles. The three-part assembly uses two guide pins to align the cage and base ring, with an oval locking pin securing the connection. A padlock prevents removal until unlocked, allowing a partner to retain the key for consensual chastity arrangements.
Choosing the right fit: The cage measures approximately 4.75" long, with a 1.6" internal diameter. Measure your fully flaccid penis and the circumference around its base and behind the testicles before fitting. The shaft should fit inside the enclosure without constant compression at rest. Select a base ring that remains secure without pinching or restricting circulation.
Check that the curved cage does not press against the penis when sitting, standing or walking. Begin with short periods to assess the fit and inspect the skin regularly. Remove immediately if you experience pain, numbness, swelling or changes in skin colour.
In the box: Blue Line Prisoner Cock Cage in Black, assorted fitting rings, guide pins, oval locking pin, padlock and key.
