I found this on Ebay. I'm sure someone has a use for this stuff right now. I bet it would make a killer replacement for a stainless braid. Not sure how rigid it is though...
It looks like it might work for a hopback of some kind, or maybe a sparge arm. I think its too big in diameter for a MLT unless its for huge batch sizes.
It's really just a problem of dead space because it won't really pull a siphon with the holes on top. The other problem is that the open space is pretty low on perforated stainless as compared to the braid because bits of grain do plug a lot of the holes in false bottoms.
