Double hung window pivot bar

Thanks for reaching out to us. It looks like you have an old Thermalgard or Amacor-style pivot bar. Unfortunately, we don't sell an exact match for it. However, take a look at the 26-262. With some modification, you might be able to adapt it to your window, though we can't make any promises. Review the specifications and see what you think.
