This is a Skinny Bun insulated bulkhead for refrigerated semitrailers, manufactured by Signode.
Confirm the part fits before you buy. Applications and interchange numbers are researched and audited per part.
We don't publish fitment for this part yet. Rather than guess, get it confirmed against your truck in under a minute.
It features a built-in walk-through door and a pre-installed fan kit to circulate air between compartments, making multi-temperature operation possible. The bulkhead divides a trailer into separate temperature zones while absorbing impact, resisting moisture, and providing easy sanitation. It is typically replaced when a trailer is upgraded for dual‑temperature use or when an existing bulkhead is damaged and can no longer maintain temperature separation.
