Yes 4 screws.
Two of them are behind the white plastic caps .
Make sure that divider hasn't slid down allowing air to go up over top.
I found it best when I installed my bedroom a/c to cut about 3" - 4" strips to seal it versus a long piece as by time you get the long one up in that little space it's no longer a useable piece of aluminum sealing tape.
