The 20 ft main-deck pallet for 747 freighters. Two of these span the deck; the max gross weight is the binding constraint, not floor area.

Contour applied
A pallet has no height of its own — the build is bounded by the contour of the compartment it sits in. The table below lists the profiles this ULD type is rated for; the same PMC is limited to roughly 64 in on a wide-body passenger lower deck and up to 118 in in a 747 or 777 freighter main deck.

Recorded as compatible with: B747F. Compatibility here means the compartment accepts this ULD’s section and the position exists — it is not a statement that the deck’s height limit allows a full-height build.
