My husband and I bought a home a few months back and a lot of the window grilles are falling off the window. The clips that hold them are broken. Its a beautiful log home and the window looks better with the grilles in them but I can not find the clips anywhere. We were told they were Pella windows. They are not. I contacted Pella and Anderson and they both said they were not their windows. I now have a picture of some numbers in the lower part of one of the windows but I don't know how to find out what brand they are. Also I have a picture of the clip I can attach to see if anyone else has them or knows anything about them. I do know the house was built in 2004 we are in Hazle Township Pa 18202 if that info is needed. They are wood windows with wood grilles. The window pulls in from the corners to clean but it is not that easy to do, you have to pull them out of the frame. If needed I can attach a picture of the window as well. Thank you for any help you can give me.
