This shim is a handy piece of equipment for feeding pollen patties, winter patties or to provide space for medication. This rim is placed between the inner cover and the outer cover of the hive to create a 1 1/2" space. The same size as our wooden hives, but can be used on Beemax hives as well. They come unassembled, but are pre-drilled and include screws. The entrance can be sealed with a plug which can be removed for a winter entrance or for ventilation in the summer.
The 10 frame shim fits both 10 frame wooden hives and BeeMax hives.
