Put the rope around the top to the bottom, set the WS in at the bottom and pull the rope slowly and get the corners started at the bottom you may have to use the SDriver on the corners and be easy and keep presher on the WS from the outside pull up on the rope on the sides slowly and you have to work boath sides to the top corners and pull rope to centeras you work with some presher until it is all the way in. Good luck! It helps to do it with two people.
