If u are like me and have a pull up window that a regular window ac won't fit because it is too wide this is for u!  I do not have a casement window I have a pull up.  This works beautifully and cools my bedroom that has 10ft ceilings!  U will not need any of the extras that come with this ac.  All u have to do is slide it in and u have a window ac in a window u never thought possible!!
