IKEA sell a corrugated plastic tube, slit along the full length. They certainly hold the cables. I glued them under my desk to keep them out of the way. I used something like No-Nails.
After a while, they fell down while the adhesive remained afixed to the wooden underside of my desk, there is no evidence of any adhesive left on the corrugated tube.
Can anyone recommend an adhesive that will "stick" to the plastic tube and of course the underside of the desk, still with the old adhesive bearing a distict impression of the corrugations?
