You wouldn’t hold your hot coffee without a protective sleeve. Same goes for your packaged terminal air conditioner. This wall sleeve is designed exclusively for Perfect Aire® PTACs to protect, insulate and bear the weight of the unit. Sized in a standard dimension, the sleeve is simply inserted through the wall to make installation and storage of your PTAC a breeze. Bonus—a drain kit is included, so everything is ready to install right when it arrives.
