A wall sleeve is required for all new PTAC unit installations. The purpose of a sleeve is to help bear the weight of your unit as well as protect it from the outdoor elements. Additionally, it helps insulate your PTAC system. Your 42" PTAC unit fits right into the sleeve, which is mounted through masonry, steel or wood frame walls.
