Plastic 4 position entrance disc

01 · THE FOUR POSITIONS

One turn for each point of the season

Turning it on its centre screw brings a different zone of the disc into play: the large opening for a clear run during the flow, the slots to narrow the front when there is robbing or the colony is weak, the perforations to ventilate without leaving the way open, and the blank sector to close for a move.

What it actually does also depends on the hole it is mounted over: if the opening in the box is bigger than the zone you present, the position does not close what it promises.

02 · THE DIAMETER

192 mm, and which one is yours

The family comes in three sizes and the diameter is the only thing that changes between them: 50 mm for mini mating nucs, 125 mm for an inner-cover hole and small nucs, and this 192 mm for large nucs and hives.

Measure the hole before ordering, and leave the disc a flat surface to rest on all round it.

03 · BEFORE YOU BUY

Mount it through the centre hole without tightening it enough to lock the turn, but enough that it does not shift on its own with the vibration of a move. Check that every position covers the whole hole.
