Hi, this company (International Window) seems to be out of business and we're having a hard time finding the replacement roller for our patio sliding door. The door is almost 25 years old. Can you help me somehow? Thanks!

Take a look at our 81-056 or maybe our 81-176. Look over the dimensions of both rollers and see if one of these match up.
