Will Friedrich Ws12a10e Wallmaster Thru-the-wall Air Conditioner 12,200 Btu 115v fit ito Fedders Type A sleeve
The rear isn't closed (can't be) - it's got a louvered grille. The baffle adapter is just a flat piece of plastic that gets glued vertically to the rear grille (it's got double-sided sticky tape) and prevents the intake of the outside air from recycling the discharged air. If the air was allowed to just circulate in the 3"-deep space between the back of the 16.75" deep A/C and 19.75" deep sleeve, the air will heat up and the compressor will shut down. So, the BAK baffle adapter is to ensure the discharge air actually goes outside. See the little picture I cut out of Friedrich manual and edited to illustrate how BAK works (below). However, you don't actually need it! Your sleeve appears to be the same depth as the A/C, so don't worry about the baffle adapter. Just make sure you use the correct louvered grille.
