The Skinny Bun Bi-Fold Bulkhead with Fan is an insulated, flexible partition used in refrigerated trailers to separate temperature zones or protect cargo.
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.
Its bi-fold design lets it fold up and store against the trailer ceiling when not in use. The integrated fan kit (often the Super Cool II) circulates air to maintain distinct temperatures, making it ideal for multi-temp operations like hauling frozen and refrigerated goods together. The lightweight, waterproof core absorbs impacts without damage and is easy to clean and repair.
