Good afternoon, Attached are some pictures of some windows in need of repair. The base pivot pin for the widow sash is broken. The module the pin sits in is broken. The "string ballast" has broken as you can see. Im not well versed in the proper names of the window parts. I have included a picture detailing the manufacturer of hte windows. I have 6 or 7 windows that have these same problems in a client's apartment. Help with identifying the parts to order would be greatly appreciated.
Thank you,
Dave
