Metal queen excluder

Galvanized metal queen excluder. Available in standard size 410x510mm for Langstroth and Dadant hives.

This is a perforated galvanised metal sheet placed between the brood chamber and the supers to prevent the queen from climbing up into the hive, allowing the workers to pass through. The gaps are 4.14mm apart, so that the workers have free access, but neither the queen nor the drones can pass through.
