A:Answer Hi Dclee! After viewing the Installation Guide, we are showing Through-the-Wall Cabinet Installation: Option 1—wood, metal or plastic molding: When using a wood, metal or plastic molding, the wood frame should line up with the inside wall. Option 2—Plastered wall with no molding: If the plastered wall is to be flush with the cabinet and no molding is used, the wood frame must be set 1/2" into the inside wall. We were unable to locate any recommendation for the sleeve EA108T. Hope this helps! -Thanks!-
