If this is the foundation I think it is, the frames come as a single
"pre-fab" unit, frame and foundation, with the foundation part of the frame
coated with a light layer of beeswax. I bought a couple to try (samples)
this year, but haven't installed them yet. They're *very* expensive, by
the way, so unless you want to use them as a permanent fixture in the brood
body, you might want to take this into account.
They're also a kind of funky (seems flimsy) shape, compared to standard wood
frames. Does anyone know how well they work out in an extractor? I'm only
a hobby beekeeper, so it's no biggie with me.
