Tracked Wood Poles
A tracked pole looks like a wooden pole from the room and works like a track from behind. The gliders run in a channel concealed on the underside, so the curtain draws smoothly while the visible face keeps the proportions and finish of a pole.
This suits heavier curtains, longer spans and windows where a ringed pole would be stiff to draw. It also allows corded operation, which a conventional pole cannot offer.
There is more detail in curtain poles with integrated tracks.
