B.S. National Replacement Correx (NA-317/NA-320)
Put them in the drawer of your floor for extra insulation and to catch Varroa Mites.
17" x 16"
Good price and arrived on time.
Should really have wood strip at one end to prevent warping. Guess I have to add those.
Great good value
Just what I was looking for to help with mite count
Board's arrived in good time
