cloth queen excluder?

[river_rat2005]

i see alot of videos of comm. queen breeders using what looks to be a cloth queen excluder to keep the queen on one frame so they can graft from that frame and know the age of the larva. where can i get them ?

If you could post a link that would be great. Otherwise, an alternative is to confine the queen to a frame with a push in cage made from #5 hardware cloth.
