Access Denied was the premier maker of classic shastity betls. Unfortunately, after the death of its founder, the business also died. It was the hands-down favorite for quality, fit, and service. The owners of this business were long time players in the New York d/s scene. They also own a stainless steel fabricating company. The combination of dedication to the scene combined with a fully equipped stainless steel fabricating facility was unbeatable. The Access denied belt is a work of art. It is fashioned from gleaming stainless steel. All parts that come in contact with the skin (except the rear chains) are either coated with a patented baked-on plastic coating, or protected by a rubber extrusion (the waist band). This device is beautiful to behold! At about $500 it is the most expensive of the chastity belts we reviewed.

No longer made, it remains the best of the breed
Like the other devices, the Access Denied belt requires precise fitting. Measurements must be taken by at least two people and repeated s few times to guarantee accuracy. My fitting was interesting. I drove to an industrial building on easter Long Island. It was a stainless steel fabricating company. There was nothing sexy about it. The owner and his wife greeted me. I was taken to their dusty conference room. It had large windows exposed to the street. I was asked to undress completely and then a tape measure was threaded between my legs, around my penis, and between all sorts of other usually-unmeasured parts of me. When my flaccid penis length was measured, your reporter was told that his penis is exactly the average for American males. So much for your now-humble reporter's delusions of grandeur. The fitting took about an hour. I stood there as measurement after measurement was taken. Meanwhile, my hosts were interrupted by people entering and leaving. It was a humbling experience. In the end it was worth the time and embarassment
The finished belt was beautiful. A stainless steel waistband fits very tightly around the waist (a tad above your reporter's belly button). At first it felt like it was preventing breathing, but a few hours later, it was comfortable. The penis tube prevents stimulation of the penis, but interestingly also prevents the usual sensations caused by clothing moving over it. It was a very noticeable and somewhat exciting sensation.
It wasn't easy to put on the first time, but by the third try it was simple and fast. The locks are secure and the hasps are protected so that nothing short of major cutting tools can get it off without a key. The penis can not be removed from the tube when the belt is on. All bodily functions are simple, though one must sit when urinating. There is considerable dripping afterward. This requires additional TP (toilet paper) each time. Other bodily functions are not affected at all. Showering while wearing it is simple and effective. It is suggested a shower head that is on a hose be used to allow rinsing some of those now hard-to-reach areas. Sleep was no problem and there was no pain when your reporter experienced his usual morning arousal, even though the diameter of the tube was too small to permit him to become erect. He could feel some not-so-unpleasant sensation. There is no question that the Access Denied belt is the most comfortable and secure ever made.
Sadly, these belts are no longer made. Until another, reliable belt-maker emerges, this reporter's best advice is to try to find a used Access Denied belt that is a good fit. It is unlikely that you will find one that fits perfectly, but if you get one that is too large, any decent sheet metal shop that works with stainless steel can probably resize it for you.
Like any belt, the downside of this product is that it does not allow unrestricted movement of the body. You will find yourself lifting with your legs, and bending at the waist is difficult at best. Your reporter doesn't want to think about what airport security might say. Of course if you like humiliation, you can always declare that you have a chastity belt on when the metal detector starts to beep.
In summary, of all the belts available, the Access Denied product was the best made, best designed, and most secure. Since this belt is no longer available, the best practical suggestion is to try one of the penis tubes.
