Re: Why use top cleats on migratory covers? Why Not?
I don't know the exact definition of a migratory cover but in my mind it's a non-telescoping lid, with either a flat or cleated top as long as the cleat dosent run the long way on the lid as that affects airflow. Many cleated lids were designed to fit together with a cleated bottom in some manner so as to lock them in place and guarantee good ventilation. Of course that was before bee pallets and forklift loading became popular. We use all flat lids to reduce the height of the load as the pallet itself guarantees good airflow.
