Should cable elevators be used?

The concern I have always understood is static electricity.
If you can generate static electic shock with your wool carpet then use risers. Personally I would use them anyway.
But anything that raises and isolates will work. I use Cable Clamps available at Home Depot and they seem to work fine. Just a suggestion, there are many products that others prefer, I just went with economics and logic when I did it.

Only if the cables are unable to make the stairs....HA, sorry, I could not resist:) Some here devise their own, utilizing household discards, up to the imagination. There are ideas regarding such via forum search, here. If/when I decide to experiment, I would try a collection of old (pole) wire insulators. Very interested in your findings should you experiment.

Haha hah.. The consensus is there is no consensus.
Two camps and a no man's land minefield between.
I say IF you can hear a difference, then great, yes use cable elevators. If you can't, then you may use them, or skip them.
I use common toilet paper (empty) rolls for my short cables. Just one per side. Free.

I do the same as Elizabeth and noted a minute change but price is right!
