Sheet metal cassette/tray cm. 42 (12-frame movable bottom)

Sheet metal cassette/tray cm. 42 (12-frame movable

bottom) Useful for inspecting and diagnosing the health of the hive and for trapping varroa during treatment and for nomadic activity.
It is necessary to grease the box with Vaseline grease, perhaps using a sheet of oiled paper for easy removal. In this way, varroa that fall out of the frames pass through the perforated net and get trapped in the vaseline grease.
After the treatment is finished, it is possible to check how much of the varroa has fallen and get an idea of the level of infestation in the family.
Also, in nomadism, allow aeration of the family during transport.
