BeeIQ Solutions | HiveGate Adapter Plate
This HiveGate™ adapter plate blocks the hive entrance with an opening for the HiveGate entrance (sold separately).
It is reversible so that two HiveGates can be used at once. The adapter is secured to the box above the entrance. This adapter is approx 31 cm wide and would need a block at each end for 10-frame equipment.
Bee-IQ's instructions for fitting the HiveGate™ to different hive bases can be found here
