Vac Hanging

Vac hanging using tension device has anyone had problems with the sleeves slipping off and if so how did you sort the problem out.
Currently using ESL40 cups to hang with the tension extender and find this better than the vac sleeve system so anyone out want to try and give me your input.

Thank you.

It all comes down to how well air sealed the cup is.

I bought some cheap sleeve hangers off of eBay and the sealing wasn’t working perfectly even though I had 3 different cups. I improvised by adding plastic wrapper on top and it works. Not quite sure how the ESL40 seals the cup though.

The esl40 is a self sealing cup for tension hanging with a rubber band on the leg just under the knee or a chest harness, I’ll sort some pics out and show what I’ve done with the extender so you can see for yourself if you want.
