CAT II Q Installation Instructions
Installing the CAT II is basically like any other tapeless tugger. The FS has to be caught between the inner portion and the outer silicone cone. Once this is done, then the tensioner can be tightened to stretch the FS.
The CAT II consists of a "pusher" to go against and push the glans, a "puller" for attaching to and pulling the foreskin, and a "tensioner" for adjusting the distance between the pusher and puller, thus adjusting the tension.
At this point, before installing, examine the operation of the CAT II to see how it's going to function when installed.
The first step is to start with the tensioner all the way out, so that the pusher and puller are together. Then the pusher is placed against the glans. (Illustration #1) The skin is pulled as far over the device as possible, while pushing in on the device (Illustration #2). In order to install the silicone cone easily, it's best to get the skin completely over the puller. In other words, the skin should be caught on the tapered part of the puller. If your skin is too short, tape may be needed, for a time, to effectively lengthen the surface to be caught.
With one hand holding the skin in place, slide the cone over the skin and release. At this point the skin should be caught between the puller and the blue outer cone, which will hold the skin in place on the CAT II Q. (Illustration #3) If your skin is short and it's difficult to get the blue cone over it, try inverting the blue cone and then snapping it back to right side out, over the skin. If slight adjustments need to be made (a bit less skin caught on this side or that), now is the time to do it. Just work the skin out a bit at a time until it looks even. If you lose the grip, simply start over. It will become easy with practice.
Once the cone is in place, tighten the tensioner to a comfortable point. (Illustration #4) I would suggest, if wearing briefs, to leave the end protrude between you leg and the elastic leg band.
To make it a "tugger", simply install the ring to the tensioner end and hook to something with a rubber band or something stretchy. Also, it could be worn as a tugger with an attachment to the leg or wherever.
An optional ring might be used at the base of the penis to prevent scrotal stretch. (Illustration #5)
If there is a problem with the outer silicone cone slipping, it's most likely because the skin is a bit oily or there wasn't enough under the cone to start with. Wipe the oil off of the skin and cone with some alcohol.
Good luck!
