Greetings,
We are attempting to repair Milgard single hung windows by replacing the counter balancers. Please see photo. Can you determine which part number we need or is the part number printed on the counter balancer itself? The windows are vinyl and are approx. 36" x 60".
Our plan is to try to service one window. If successful, we will proceed to repair 10 more.
Thank you in advance for your help!
Jonathan
