I am looking to replace this part in a few of my windows. The roller wheel is missing in a few of my windows but this is a picture of an intact one. I do not want to remove it because it is really old and I don't want to break this working one. The roller assembly is 7/16" across. Thanks for your time

Thanks for writing in. Take a look at our 87-162. Compare it to your roller assembly and see if it matches.
