These look like fairly older style balances. I think we can help replace these but they may need to be custom made due to their configuration. Before we go any further, I'd like to verify a few details. First, can you show me a clearer photo of the metal clip at the bottom? It should be what's at the end of the retractable cord. Can you also show me how the balance installs at the window at the top, whether it be by hook or screw? I'd also like you to tell me the length of the metal channel for each size, and the weight of the sashes they support. Finally, how many of each balance did you need? |

Thanks for your patience while we looked into this. I've never heard of a balance installing on a metal plate like that. Can you verify? That would seem to me like an unstable method of holding the weight of the sash, since it's at the bottom. Without the top being secured to the track with a screw, there would be nothing stopping the top of the channel from falling in during operation. Either way, the best option we have for this configuration is an Series 770 channel balance with a 62-105 attached to the end of the cord. We can supply this, but only as a custom order. The two sizes would be our S770-12 for the 1130 stamp (12" long with a 12C stamp, for sashes weighing 10 through 16 pounds) and our S770-22 for the 2130 stamp (22" long with a 22C stamp, for sashes weighing 16 through 21 pounds). Both balances are designed to screw in at the top using a screw, not secure on a metal plate at the bottom like you're showing here. We don't sell any balance that works that way. If you are interested in these custom balances, please let me know how many of each size you need and we can work from there. |
