I notice, in addition to the usual Brushy Mt and Miller Bee Supply, that Betterbee and Mann Lake now have eight frame equipment. Betterbee has quite an assortment of accessories. Unfortunately, unlike Brushy Mt and Miller who have 13 3/4" wide hives, Betterbee and Mann Lake have 14" wide hives. I thought Brushy Mt has kind of set the standard since they were the only ones selling any number of them and accessories, but we apparently have no standard.
There must be a significant increase in demand for eight frame hives.
