CB-X U Ring No 5 Male Chastity Cage by A L Enterprises

The CB-X U Ring No 5 Male Chastity Cage by A L Enterprises is a replacement base ring measuring 38.1mm, designed for men with larger frames who need secure fit in male chastity devices. It works with all CB-X cage models to prevent slipping during extended wear. For long-term lockup, getting the ring size right is everything.

Design and build

The CB-X U Ring No 5 Male Chastity Cage by A L Enterprises is a precision-engineered replacement ring that forms the foundation of any CB-X cage system. It wraps around the shaft and behind the testicles, anchoring the entire device in place. The 38.1mm diameter is specifically calibrated for men with larger frames who need that snug tension without pinching or discomfort during round-the-clock wear.

What sets this ring apart is the precision sizing system built into the CB-X range. Rather than guessing or settling for a one-size compromise, each number from 1 through 7 is measured in exact increments so you find your perfect fit. The black polymer construction is tough enough for daily wear yet smooth enough to sit comfortably against skin for hours and days at a time.

The features that matter

• Larger opening: At 38.1mm, the Number 5 ring accommodates bigger shaft sizes that smaller rings would restrict or cut off
• Universal compatibility: Fits all CB-X chastity cage models, so you can swap rings without buying a whole new device
• Precision engineering: Each ring size is mathematically calibrated to deliver escape-proof security without compromise on comfort
• Durable polymer construction: Black finish resists wear and discolouration, holding up to daily cleaning and extended lockup periods
• Easy replacement: Swaps in and out in seconds if you need to adjust sizing or refresh your setup

Finding your size in a male chastity

Getting the ring size right is critical for any chastity cage setup. The ring needs to sit snugly but not restrict blood flow. Start by measuring your flaccid shaft diameter with a soft tape measure wrapped around the widest part. If your shaft measures 38–40mm in diameter, the Number 5 ring should be your starting point. Sit down during measurement to match how the cage will actually feel during wear.

When trying the ring for the first time, insert your penis and testicles through the opening while in a relaxed, flaccid state. The fit should feel secure but never painful. If you can't pass through comfortably, you need a larger size. If it slides too easily or rotates around your shaft, you need to go smaller. Many people upgrading from smaller Double Ended Chastity Cages find the Number 5 delivers the security they were missing. Once locked, the ring should stay exactly where you put it.

Who should buy it

Care and storage

Wash the ring in warm soapy water after each removal and dry it thoroughly before reassembly. Use a soft cloth to avoid scratching the polymer finish. Store it in a clean, dry place away from direct heat or prolonged sunlight, which can weaken the material over time. Inspect it regularly for cracks or stress marks, and replace it if damage occurs. Proper care keeps the ring smooth and comfortable for years of reliable use.

Dig deeper

Understanding how sizing affects your chastity experience matters far more than most people realise. A ring that is too large causes constant worry about escape; too small creates pain that derails long-term wear. The Number 5 is engineered to solve that problem for larger men.

What to expect

Men upgrading to the Number 5 from smaller rings often report an immediate sense of security they were missing before. The shift happens the moment the larger opening allows comfortable insertion without strain. You stop thinking about whether the cage will slip and start focusing on the actual experience. That psychological shift is often more significant than people expect.

First-time users should allow a few days for the ring to settle. Initially it may feel noticeable—you will be aware of it constantly. By day three or four, most wearers report that awareness fades into background sensation, though any movement or touching the cage brings it back into sharp focus. This is normal and exactly how the device is meant to feel during extended wear.

Cleaning is straightforward: remove the cage, wash the ring in warm soapy water, dry it completely, and reassemble. Most people establish this routine within a week. The polymer construction is durable enough for daily cleaning without degradation, so you need not worry about handling it gently. Over months and years of 24/7 wear, the surface may develop a soft sheen but the ring itself will not crack or weaken.

Long-term wearers find that the Number 5 ring performs best when paired with consistent hygiene and a keyholder who respects the security of the lockup. Men who slip in and out of chastity frequently may experience irritation simply from repeated friction, not from any fault in the ring. Those who commit to extended denial periods find the ring becomes almost invisible once the initial adjustment phase ends.
