Clamps and other aids

I was looking at some of the members pics and I saw a guy wearing a “clamp” and I’m wondering where I can get one from. I saw some other device for hanging. Where can I get these things and how much do they run? If you know of any other devices let me know about them and how much they are.

It’s called a Cable Clamp and they’re found at Walmart and Home Depot.

You should probably note that it’s reccomended to have been PEing for around 3 months atleast before moving onto clamps/other aids, just so your penis is conditioned and it’s less likely you’ll injure yourself.
