You'll never struggle again with installing a queen cage in your hives. Whether it is in the spring with a new package or you are re-queening during the season. This will take all the worry and fumbling that comes with other methods. Fits standard woodend queen cages and will last for years. Come with a hole at the bottom for those that prefer removing the cork at the bottom instead of the top.
Just uncork one end, place in installer and hang between two frames. Can be used with new frames or with old drawn out comb.
