Model Comparison of the families of products that we offer. 


CB-6000, CB-300, The Curve

The first consideration is the size of your flaccid penis. The CB-6000 will accommodate a 1 3/8″ diameter and about five inches in length. CB-3000 is slightly shorter, but slightly wider than the CB6000. If either dimension are greater than that, the Curve may be the better choice. There is also the CB6000-S model, which is an inch shorter than the regular CB6000, and has been very popular since it’s introduction.

Another consideration is appearance. While all models are pretty discrete under loose-fitting clothing, on most men the CB-3000 and CB-6000-S will be the one least likely to be detected. The CB-6000 is also quite discrete. The Curve does protrude out further than other models, but if you are large enough to wear this model,chances are that the bulge in your trousers has been noticed before.


Birdlocked, Dick Cage, Bon-4, PICO, PA & NEO

Birdlocked Classic Model :
This is our best-selling model. Over half of our customers order the transparent model with a Ø 45 diameter.
Birdlocked Mini Model :
for those who want to feel a bit more pressure.
Birdlocked Maxi Model :
For those who need more space.
Birdlocked PICO Model :
With its small silicone spikes.
Birdlocked PA Model :
Designed specifically for those who wear a Prince Albert. This is unquestionably our most secure mode.
Birdlocked Neo:
It adapts perfectly to all body (45 to 52) and naturally shaped apparatus that molds itself around the lower stomach and penis.

Birdlocked models are all one piece, and have six models that come in a variety of colors and sizes. Since its introduction in 2010, the Neo model has been by far the most popular for two reasons primarily:

The ring design accommodates a range of 45mm to 52mm, somewhat self-adjusting. It is designed to be more secure (i.e. more difficult to get out of) than earlier models. Dick Cage was introduced in 2011, and does a very good job of trapping the penis to prevent escape (though none of the models are fool-proof). It is available in clear and black versions, and is available with three choices for ring-sizes and two length of cage.

  Maxi                        REGULAR                        MINI
Total Length:                      4-1/16″ or 105mm      3-3/4″ or 95mm                   3-5/16″ r 84mm
Tube Length:                      3″ or 75mm                2-1/2″ or 65mm                  2-1/16″ or 55mm
Tube Diameter:                  1.5/16″ or 33mm        1.5/16″ or 30mm                 1.3/16″ or 30mm
Ring Width:                        1-1/16″ or 30mm        1-1/16″ or 30mm                 1-1/16″ or 30mm
Ring Inside Diameter:  The rings are available in 4 sizes, depending on the color and tube size you need.  The size (1-3/4 inches for example) refers to the
width across the top area of the ring.  The ring then tapers as it goes down, getting narrower.

If you have worn a 1-1/2″ or 1-5/8″ ring, get the 1-1/2 or 40mm ring size BL.
If you have worn a 1-5/8″ – 1-3/4″ ring, get the 1-3/4″ or 45mm ring size BL.
If you have worn a 1-7/8″ or larger ring, get the 2″ or 50mm BL.
If you need a ring larger than a 2″, get the 2-1/8″ or 53mm


Bon-4 comes with multiple rings to help find a good fit. Like Dick Cage, it has a choice of short or long tubes. There is actually the “Plus” model which contains both tubes. The Bon4 is a CB that it is extremely hygienic, durable, and considerably more comfortable that devices made of other material.

Featuring four sizes of flexible silicone cock rings that interlock with the comfortable silicone cage, the device is adjustable and will fit anyone. Simply choose the cock ring that fits best and fit it around your penis; attach the cage and interlock them with the included belt; then lock things down with the extra secure padlock. Enjoy the erotic physical and mental arousal of having your most intimate areas under lock and key, or locking up your partner!

There are 3 holes in every cage,  2 holes for ventilation which also can be used for cleaning and 1 to urinate.  The holes are relatively small and make it impossible for any personal stimulation.

A few tips to keep your BON4 in good shape:

•You can wash your BON4 with a mild soap or sterilize in boiling water (2 minutes)
•Keep the BON4 in a dry place, not in plastic and not in the sun.
•It is always a good idea to store the BON4 in the original package.
•If you choose to use a lubricant, which is a good idea when you put the device on, it will be best to use a water based
•Do not use oil or silicone based lubricants. (unless it is olive oil)


Holy Trainer v2 – latest evolution in male chastity The Holy Trainer is made of a 100% natural biosourced resin. This material is being used more and more in very diverse areas such as aviation or electronics. Biosourced resin replaces traditional petroleum-based resins.

The ring shape is perfectly suited to the anatomy of most men. Because it slightly curves outwardly, there is less stress on the testicles if an erection should occur (compared to other male chastity devices).

The new Holy Trainer locking system (called “Magic Locker”) enables the closing of the device without a padlock. It slides through the ring & tube to hold them together. The sheath includes 3 ventilation holes for comfort and hygiene.

Strict Gate

Introduced in December 2016, the maker of the Birdlocked and Holy Trainer produced a hybrid using the best features of both product called the Strict Gate.

It incorporates the thin and ergonomically shaped ring of the Holy Trainer with an attached with a comfortable silicon tube, comparable in size to the Birdlocked Classic. The tube is attached to the ring by a cord, making it a two-piece assembly tightly bound together.

BON4M Stainless Steel Chastity Device

For those who would like a real serious male chastity device we offer the BON4M and the BON4Msmall. A special design produced in rust free stainless steel which has been tested and is very secure. The polished stainless steel chastity cage comes in two different sizes each with 4 different sizes of stainless steel hinged back rings.

The BON4M is designed as a Medium/Large sized chastity device while the BON4small is more a Small/Medium sized chastity device. The approximate gap between the base ring and the cage is around 11mm. That’s the space we think is best to still be able to put the device on easily and prevent escaping, thus having an extra secure device.

There are also two additional sizes of hinged back rings available: 36mm (1.4″) and 56mm (2.2″) diameter. These can be purchased separately if needed.

Common Questions:

Should I use a lubricant?

We do not suggest using any lubricant on the inside of the tube. We suggest that you stay clean and dry inside the tube. You may want to put some good quality hand lotion (Vaseline Intensive Care, Nutragena, etc.) between the inside of the ring and your skin. That will help with movement during the day and night. The manufacturers of the silicon models all say to avoid using silicon based lubricants, as it could cause the material to degrade. Finally, we recommend avoiding any product that cautions against oral ingestion in any form – if you can’t swallow it safely, then you shouldn’t be applying it to your skin.

What Kind Of Hygienic Supplies Should I Get?

You will need an Angle Tipped Squirt Bottle and Cleaning Swabs, some Q-tips, body wash, talcum powder.

What Kind Of Care Should I Give The Lock?

Ever 1-2 weeks put one drop of oil into the lock. Use a multi-purpose oil or something like a WD-40. Even though the locks are made of brass they will get corroded inside.

I Have Swelling and/or Discoloration.

Either the Cuff Ring is too tight or you do not have enough spacing between the Cuff Ring and the tube. Try the next larger Cuff Ring if it is uncomfortably tight or use a bit more spacing, which will possibly necessitate a longer locking pin and spacer.

I Have Pain During Arousals.

Is the pain from the CB pulling on the underside of your scrotum? Unless the Cuff Ring is just too tight, that is something that you will have to live with. Your body will adjust. However, if there is undue swelling and/or discoloration, take off the CB and make adjustments to the Cuff Ring size.

A good suggestion – after you get your CB on, pull back all excess scrotum skin so that what is hanging on the outside of the ring is tight, not loose. There should only be enough scrotum hanging on the outside of the ring to hold the testicles.

In The Morning I Have A Hard Time Urinating.

That is probably because you have woken up somewhat aroused. If the opening at the end of your penis lined up with the hole at the end of the tube, you’ll be fine.  If not, take a Q-tip and try to move it to where it is lined up.  Now, try to relax.  Sit on the toilet (lid open!) and pull out on the lock trying to stretch the unit and straighten out your shaft. Try making some short bursts of liquid. You will find that it comes out rather easily.

I Find That I Leak A Little Urine Or Seminal Fluid During The Day

After urinating, take two fingers and “chase” the remaining fluid out of your shaft. Do it by placing the two fingers firmly between the scrotum and anus and using pressure, move the liquid forward to the ring. You will get most out that way.

My Head And Shaft Get Dried In The Tube

That can be caused by an excess of soap residue being left after either getting fitted or after cleaning. Make sure that you flush the soap and/or the lubricant out of the tube. Get a great Angle tipped Wash Bottle here.

How Do I Stay Clean For Daily And/Or Long-Term Wear?

In the morning and evening, take either a squirt bottle or shower stream and get some water inside the tube. Use the Cleaning Supplies like the Angle-tipped Water Bottle and Cleaning Swabs. Now, squirt some soap into the tube and work it around with a Cleaning Swab or Q-tip. Use the squirt bottle with clean water and flush the soap out from the inside of the tube. Now, using some Q-tips, try to get as dry as possible inside the tube. Do not let water get trapped between the tube and the scrotum or under the Cuff Ring or you will get chaffing and odors.

Can I Swim, Run, And Have Other Physical Activities While Wearing A CB?

Yes! If the sport is extremely fast-paced, you may want to use an athletic supporter. Otherwise, you will be fine.

How Do I Deal With Frustration And Mental Anxiety While Wearing A CB?

Putting on a CB will not be as hard to get used to physically as it will mentally. All of a sudden you have something that is very important taken away from you. You can no longer touch it or stimulate yourself. The best answer is “just deal with!” Hopefully, the Keyholder is kind and will not just leave you alone. There should be some good play and attention given to the male. He’s not as strong as he makes himself out to be. After a few months, the CB will be a normal part of your lifestyle. Both physically and mentally you will become accustomed to it to the point where when it is taken off you will look forward to getting it put back on again.

If possible, get your mind off of the fact that you are locked up. When anxiety hits, go for a walk, call a friend or your KeyHolder, get involved in a hobby, go to the store. Also, you might want to interact with others on a couple of message boards: and You will find others who have probably experienced just what you are going through.

The Lock Rubs On Skin Poking Through Vent Holes

Again, use some clear packing tape and put it over the vent holes.

Can I Make It Through The Airport Security Check With A CB On?

Aside from the metal ones, they are all plastic or silicone and will not trigger a metal detector. If you are concerned about the lock, use plastic locks. However many airports now have full body scanners and detection is likely.

  1. How long does a PA piercing take to heal enough to use a PA 5000 ?

    1. Hi Rodger, it would probably vary by your hygiene, but I would think at least a week.

    2. Mine took probably 4-6 weeks before I would have attempted any of that.. The more you soak your penis in salt water, the quicker it will heal!

  2. is there any way to pull the penis out once small i have one now i can not remove from my balls but can get the penis out and put it back in
    not sure how to measure as well for this what pins are you talking about that can go with it miles

    1. Hello Miles,
      I’m not sure what product you are referring to, but I think that you are asking about the Guardian device that we have for both Holy Trainer and all CB-X models. There are versions that have rubber pins that extend into the tube to help prevent someone from pulling the penis out of the tube.

      Does that help?
