Keystone 26 in. Wall Sleeve for Through-the-Wall Air Conditioners

The Keystone 26 in. wall sleeve for through-the-wall air conditioners should be securely fastened within a wall opening before installing the air conditioner. The sleeve helps bear the weight of the air conditioner while keeping it insulated and safe from dust, bugs and other debris that could get sucked into it. Inclement weather, corrosion and other elements cannot match the protective power of this metal sleeve.

• Bears the weight of the AC while keeping it insulated
• Keeps AC safe from dust and bugs that may get sucked by the AC
• Durable sleeve is weather- and corrosion-resistant
