They attach to just about any type of tubing up to 7/8" O.D. The folded wick design allows for maximum burn time without the added weight of too much wick. This wick design also allows the wick to spin freely around the cable, thus dramatically increasing the lifespan of your wicks! This flexible yet sturdy cable spine design measures 5" long from hoop to edge of spine. It comes with a LIFETIME warranty on manufacturing and fits up to 7/8" tubing (When used on smaller diameter tubing there will be a slight "tail" that sticks out).
