These one-piece food-grade plastic frames coated with beeswax are ready to use - no
assembly required. The frames are 6-1/4" " for use in standard medium boxes. They are available in either black or white. The black color makes it easier to see eggs and young larva
during brood inspection. The white is often used for honey supers so "your honey frames" are easy to identify.
The sturdy one-piece construction means you never have to worry about the frames coming apart in the extractor. These frames are reusable - just scrape off the old comb, power wash & give it a quick coat of wax, and they are ready to go.
have found that adding an additional coat of wax before installing in
the hive helps the bees accept and draw out the new frames more quickly.
