IDENTIFY YOUR EXISTING SLEEVE

What fits the Friedrich USEZ sleeve?

Friedrich USEZ sleeve identity and sourced opening dimensions. Manufacturer documents disagree on outside dimensions, so the listed installation outcomes require clarification.

No confirmed replacement options in this reviewed record.

Confirm this is your actual sleeve. Each option has separate installation and electrical requirements.

How to identify it

Confirm the exact USEZ part number; dimensions alone do not establish compatibility.Source 99
The exact USEZ assembly manual specifies a minimum 26.25 × 15.75 in finished opening. Its external dimensions remain disputed with the combined USC/USEZ brochure table.Source 100

Dimensions: three different measurements

Interior dimensions, outside sleeve dimensions and the wall opening are different. These values describe the equipment; they do not prove fit.
