Re: Plastic Foundation in modified Dadant (Dadant US)?
Check European suppliers for plastic foundation in Dadant size, particularly suppliers in Germany, France, and Italy. These countries have robust beekeeping industries based on various types of Dadant hives.
Dadant still has several cases of Duragilt in modified Dadant size. Call and ask specifically for it and they will gladly ship you a case.
I had Dadant manufacture 200 pounds of wired wax brood foundation for me a year ago. If you want some wired wax in modified Dadant size, I can send you a box of 60 sheets for $2 per sheet plus shipping.
If you want other sizes, sometimes Dadant will run a special order of wired wax brood foundation that is not cut. They just run it off as a roll and put the roll in a box for shipping.
