Measure around the base of the penis and scrotum. Use the circumference you take and use it to find your diameter measurement.
The base ring is approximately 10mm thick.
Make sure to measure when you are flaccid. Take a circumference measurement and use it to find your diameter measurement.
Make sure to measure when you are flaccid and let the penis hang naturally. Measure along the top of the penis from the base (where it meets the body) to tip.
(Cage length) = (Length of your flaccid penis) - (Parallel spacing) - (Thickness of the base ring, approx. 10mm)
Usually the parallel spacing is between 6 to 12mm. This space is for the skin of the scrotum on either side of the base of the penis. The smaller the parallel spacing, the tighter the lock.
This space is used to hold the testicles in place and is usually between 9 to 15 mm. It's based on testicular size, if it is too wide the the testicles can slip through the gap.
Most chastity cages can be made with or without a welded PA at no extra cost. The adapter ring is used to weld either a PA or urethral tube onto it. If the diameter of the PA is small, we recommend choosing a sold PA, it should be at least 3mm. Let us know what diameter you need.
Detachable PA
If someone has a small PA hole but they want a urethral tube, we can make a diameter-varied PA accessory and fix it to the adapter ring with a screw. A solid PA rod is at least 4mm and a hollow urethral tube is at least 6mm to let urine flow through the tube. Adding a detachable PA costs an extra $115 CAD or $80 USD.
Some chastity cage styles have the option of adding a urethral tube. The tube diameter can be customized. Adding an urethral tube costs an extra $115 CAD or $80 USD.
If you are choosing a PA with a urethral tube, let us know the diameter of the Urethral tube along with the PA hole. A hollow urethral tube is at least 6mm to let urine flow through the tube.
