I don't think I'd encountered the suggestion to use a PVC sweep to ease
the strain on the cables. I used "Kellem grips," secured by small hose
clamps to the loop on the top standoff, to suspend the cables -- either
individually or in small bundles -- leaving some slack above.
I've never found Kellem grips in the "home improvement" stores, but my
local "real electrical supply houses" stock them.
