Plastic frames are an efficient time saver. Molded right here in the USA from food grade plastic, they are ready to use and require no assembly. They are impervious to wax moths, offer 15% more brood rearing area and have reinforced ears to reduce the possibility of breakage.
Frames come in your choice of black or white.
We prefer to use black in our brood chambers because it makes seeing developing larvae easier. This is especially helpful if you are grafting.
