WHAT IT IS: This galvanized metal disc is a versatile tool to use on a nucleus hive or a swarm trap, creating multiple entrance sizes with the adjustable disc. The round disc has a center hole for securing to the box with a screw or nail and 4 different sized entrances to be used.
HOW IT IS USED: Most often used on swarm boxes and nucleus hives, the disc rotates over a drilled hole in a box, allowing the beekeeper to easily modify the entrance. These entrances are especially helpful when setting out a bait trap; leaving the entrance open and rotating it closed when it's time to move the swarm hive.
ENTRANCE OPTIONS: Closed, vented, queen/drone excluder, and wide open with a 1 3/4-inch opening.
