You only need to replace the top sash guides or take out clips if they are broken, brittle, or missing; it would be a good idea to keep a pair of top sash guides on hand in case one does break upon installation of the new balances.
My balance is stamped 24 4 Caldwell HM. The cord broke and I need to replace it. Is this a stock item or special order
You will need to replace the entire balance, not just the cord.
If you can't identify the appropriate replacement, submit a few photos of your balance attachments and any markings you may find on the balance. Also include the length of the channel portion of your balance.
Why can't I replace the broken cord in a channel balance, there are no other broken parts and the balances will still be the same matched pairs. I think it is unnecessary to replace the whole unit.
My channel is stamp 27 4 GN caldwell please let me know whitch one I need and how many per wendow do I need. I need for 2 widows. Thank you.
27 4 indicates the length of 28" and the weight stamp option of 2740. We can help you determine the series of balance you need if you send us some photos of both ends of your balance.
