hellow my jeld wen window was opened too far and the black piece that fits flat on the casing that holds the are in place has 3 black holes and the last hole that the little arm has attached in ripped so the small arm will not stay in place thus making it hard to close window. The piece is about 2 to 3 inches long and is black with 3 small holes in it and the base of the window arm that opens and closed the window sits in that piece.
Let me know if you have the piece and maybe you could send me a photo
thank you Julie
