Replace window channel balance

We can help replace these balances, however three out of these four will have to be specially made. Before we begin, I'd first like to confirm the Series. I see you were looking at our Series 370. Is this what you have?

Regarding these stamps, the three that need to be specially made are the 35DS37, the 35DS55L, and the 29DS48L. Can you tell me how many of each you need?

As for the 2950, this would just be a regular ol' S370-30 with a 2950 option. No special order needed.

Once I know how many you need of those three balances, I'll email you a special order link and price quote for each.

The Series is determined by the nylon attachments on either end of the balance. The Series 370, for example, has a 19-004 at the top and 15-002 at the bottom. Are these what you have? If not, or if you aren't sure, please take a clear picture of both the top and bottom nylon attachment on your current balances and upload them here for us to see. Please make sure they are as undamaged as possible!

Once we have the Series figured out, I'll shoot over those order links.

Thanks again for waiting. That's a huge help, yes. We will be going with our Series 385 for these balances.

For the 2950 balance, I recommend our S385-30 with that same stamp. This doesn't have to be custom made, it's just one of our standard balances.

The same goes for the balance stamped 35DS37. This will be our S385-36 with a 3560 option. No need for a custom order!

The remaining two will have to be specially made. I will email you a special order link right now for 4 of the 35DS55L and 4 of the 29DS48L. Let me know if you have any questions!

Yep, it's because the strength of the spring exceeds any standard option. If you were to use a standard option balance for any of your springs, they would be too weak. Your window would fall down every time you tried to o pen them. Based on your stamps, all of your windows are exceptionally heavy.
