Dustpan,
If I am getting this right, I think this is the easiest- most convienent -- cheapest home made hanger out there. Did you think of it on your own? Shall we call it Dusty's penis muzzle

?
I will have to make one. I have a few questions.
When you said "you will need one or two clamps to clasp the outside," do you mean cable clamps?
Also, specifically, what type of muzzle is that? Some of the muzzles I was looking at seemed to be to big for this.
