SWISCO - The Replacement Hardware Authority

Milgard balance unit

A home owner from USA says:
I have had 2 window balance units fail where the strings are tied in knots at the top of the balance.
The windows are a little over 1 year old. I contacted Milgard and Window dealer and it took almost 2 months to get replacements. I have 4 more windows like these and anticipate having the same thing happen with them. I have detailed the info for the balance unit below.
Thanks
Pat T

Thank you for your patience in this matter. We may be able to help, but we just need a bit more information. Before we go any further, can you tell me if you have "P280 or "P281" printed on your bottom guides?
