All you have to do is measure the different types...

Different suppliers source their wares from various manufacturers and each
is slightly different...

By being aware of the racial type of your bee and it's morphometric
characteristics, you can tune the excluder to suit the bees.

I do have two more types of QX that have not yet been photographed and
measured... They will be added within a few weeks.

However do not expect to ask the supplier what the figures are for what they
supply, in the same sense that many consider that the cellsize of foundation
is 'standard', many think that queen excluders are all the same.

The principle is even applied to a wider spacing drone 'excluder' to enable
drone retention...
