8FR Betterbee Shim
This shim fits 8 frame wooden hives. It is a handy device for top feeding pollen substitute or applying pesticide patties. Place them on the top of the frames of the hive body to create a 1-1/2” space. They come unassembled, but are predrilled and include screws. The entrance is seal-able with a plug which can be removed for a winter entrance or for ventilation in the summer. When using the shim to apply pesticide patties that fumigate the hive, the hole should be plugged.
