Hi Helen. It think we can replace these balances for you, but I'd like a little more information just to be able to identify a replacement. Could you show us clearer pictures of the top end attachment? It's hard to make out in the one photo you show of it. Could you also confirm that the length of the metal channel, not including the end attachments, is 28"? Many thanks. |

Hi Helen, thank you for your patience. I joined this conversation late, so bear with me. I actually think you might be comparing the parts too exactly. If your window sash uses the 18-124P top sash guides, you have a Rollyson window. Back when I used to replace the balances on this type of window, I used our Series 371. The series 371 uses the 19-031 top fitting and the 15-005 bottom fitting on the balance channel. For your 28" channel balance, I would recommend S371-28 with a spring option of 2740. I am confident they will work for your sash. |
