Commercial-grade, Thru-the-wall, Perfect Fit for a 27" Sleeve

Once installed, there is no discernible gap between the unit and the sleeve, for a clean, finished appearance and minimal intrusion of outdoor air.
Built with the best commercial-grade materials and components, WallMaster is durable yet quiet. Its solid-side sleeve assures maximum performance in thicker wall applications and gives you multiple installation options. Plus, the Baffle Adapter Kit expands the depth of sleeves that can accommodate WallMaster.

Designed specifically for thicker wall installations
Unlike solid-side thru-the-wall air conditioners, window air conditioners have side vents. Covering an air conditioners side air vents (as shown to the right) can restrict air flow, diminish performance and potentially void your warranty so we strongly advise against it. Our solid-side sleeve has no side vents. You can install it through walls up to 15 5/16" deep without compromising performance
