I subscribed because I am very interested in hearing more about this!
Ok, I’ll jump in here.
The small kids finger trap was a fun toy to play with.
But I don’t think there is a larger version unless you look in the industrial section of Wire and Cable.
Some telephone cables are over 4 inches in diameters. These slop over the cable and attach to a cable and pulled through a conduit.
But these are made of stainless steel and although they will hold you tight, it is steel and it could cut off your blood flow.
I think real latex gloves with a steel ring at the end is a better option.
Once you put your hand and arms in, and you sweat a bit, you’re not going to get out too easily.
Also, a good strong pair of nylons/pantyhose will work just fine.
I know that Ra has a thread about using pantyhose as an armbinder that’s really easy to get into, but very difficult to get out of.
Hope this helps.
