This is a larger version of the classic ANEL pollen collector. Thus, you get ALL the advantages multiplied! More than two times larger pollen collection area. Larger flight board on the tray. Larger rain cover. Better drawer attachment so that it is not affected by wind or bugs. With specially designed gaps that do not injure the bees while retaining 60% of the pollen so that there is no danger of pollen deprivation for the hive. PLUS … it features an incredibly simple way of attachment to the ANEL-PCCLIP hive. It has two points of protrusion, right and left, that are pushed in the hive entrance; the collector is supported on these two points.
