The Iron Threading Queen Excluder helps eliminate the risk of losing your queen or having brood in the honey supers during the extraction process. When brood is present in the supers, it is nearly impossible to clear bees from the combs using a bee escape. This excluder ensures that the queen and brood stay in the brood chamber. Our metal excluders are welded with precision wire spacing through computer control, ensuring longevity and reliability. Each wire is crimped into the frame for durability.
