IDENTIFY YOUR EXISTING SLEEVE

What fits the Friedrich USC sleeve?

Manufacturer-documented USC sleeve for the reviewed R-32 Uni-Fit models. New installations require a separately purchased sleeve; use the exact manual and supplied installation parts.

10 documented options. 10 with required kit included.

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

How to identify it

  • Confirm the exact USC part number; dimensions alone do not establish compatibility.Source 99

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.
