Can you help me in replacing these? I have a few window that will not close. They are Hurd windows from about 2002.
Thanks!

This looks like either the 39-253LB & 39-253RB , or the 39-438B & 39-439B . The difference between these two operators is illustrated in the video below. Take a look and see what you think.
