The CB-X U Ring No 5 from A L Enterprises is a replacement ring component for CB-X chastity devices that provides the perfect fit for larger shaft sizes. Measuring 38.1mm, this ring ensures your cage stays secure and comfortable during extended wear. Compatible with all CB-X models, it delivers the snug, escape-proof fit that makes long-term lockup possible.
The U Ring is the foundation of your CB-X cage system. It sits at the base, wrapping around your shaft and behind your balls, holding the entire device firmly in place. When you find your exact size, you get that perfect tension—not too tight, not too loose—that keeps everything secure through the day and night. If you've outgrown the smaller rings included in your kit, moving up to the Number 5 gives you that snug lockup without discomfort. Browse our adjustable cock rings to see other sizing options available.
What makes the CB-X system different is the precision engineering behind these rings. Each size is measured in increments specifically designed so you find your perfect fit. No guessing, no compromise—just that satisfying click when you know the cage is staying exactly where it should be.
| Ring Size | Best For | What Makes It Different |
|---|---|---|
| Number 1-3 | Average to smaller frames | Tighter, more compact fit for men with standard sizing |
| Number 5 (This Ring) | Larger frames and bigger guys | Provides 38.1mm opening for comfortable, secure long-term wear |
| Number 6-7 | Biggest builds | Maximum opening for men needing extra space without sacrificing security |
Men with larger frames: If you've tried CB-X devices before and found the standard rings too tight, the Number 5 gives you that secure fit that actually works. You get the control you want without the pinch or discomfort. Check out our full range of cock rings to explore all your options.
Long-term wearers: Guys doing 24/7 lockup need a ring that won't shift, rub wrong, or cause pain over hours and days. This size delivers that perfect tension that lets you forget the cage is there—until you remember exactly why you wanted it locked.
You need a ring that doesn't compromise. Too small and it cuts off. Too big and you slip out. The Number 5 hits that sweet spot for bigger guys, giving you escape-proof security that lets you fully commit to chastity without worrying about the fit. It's the difference between a device that works and one that actually stays locked where it counts.
Real experience:
I ordered the Number 5 because the smaller rings weren't cutting it for my size. The moment I swapped them in, everything changed. The cage finally stayed exactly where it needed to be, no shifting, no slipping out. It was the missing piece I needed to actually get into long-term chastity without constant adjustment.
Wearing it feels right—that perfect snug pressure that reminds you constantly that you're locked. The psychological shift is intense when you finally have a cage that fits properly. You stop thinking about whether it's going to slip and start thinking about the power exchange itself. That's when the real experience begins.
