Did you bother to read it? It's for crates and pallets, 36" is pretty much the standard. No mention of caskets in my read…
It's a standard shipping contract. If I needed to create something to send it overseas, we didn't have arts and crafts, we called a number and the contractor built a sweet ass box complete with custom foam. Most supply depots/squadrons have this.
Besides, gov caskets are aluminum and designed to be packed with ice. Spent time at the Dover Mortuary, never again.
Huh, phone fagging, must have fast fingered scrolling, I stand corrected, it does clearly state caskets… my bad, I'll go stand in the corner.
