I have a trio of hanging pendants, which hang from white cords that
don't hang quite straight. I'd like to find a set of stainless or
brushed-nickel tubes, to cover (and straighten) the cords with, in {12",
18", and 24"}. Sofar I've only found "hang straight" tubes in black or
white, 48" or 96". Anyone know of a lighting-accesory website, or the
right keywords for google?

Gracias,
JSH
