>>I was wondering if any of you are familier with the company Dadant. If so they have a foundation for brood called Duraguilt(or durabuilt) TM and I was wondering what the difference was. And since the Duraguilt has "communication holes" that if those would make a difference as well. Thanks in advance.<< Aaron, I only use Duraguilt in the brood chanmbers because it saves time and labor. In my honey supers I use both Duraguit and Pierco plastic frames and foundation. This works for me. By the way is Norris in West, Middle or East TN. I am in West TN. Bill Hughes Bent Holly Honey Farm Brighton, TN
