Hello. We are trying to find balance rod replacements for several of our windows.
The one in the photo is stamped with 2919, we need about 20 of these including the plastic sash cams. Do you have parts available? Some of the others we need are stamped with 3428. I believe we need 10 of these along with cams. I think we have one other size we need as well but I left the list at home. Thanks.

Your stamps are very peculiar. I've never seen channel balance stamped use those designations. Can you show me a picture of the 2919 and 3428 stamps? Can you also confirm the weight of the sash in each case? As for the balance itself, I'd like to know the depth of the bottom shoe, shown in your second photo. Another way to think of the depth is the "heel to toe" measurement. Thank you! |
Hello. Here are the additional photos you requested. I only have the 2919 rod that is accessible. The rest of them are still in the windows. The windows were removed to get the numbers however.
The windows were ESP installed around 2006ish. The locks and the emblem on the glass both say ESP. The emblems on the glass are really hard to make out, most information is not readable. They are impact glass windows using the glazing technology between to panes of the glass to get the rating at the time.
2919 need 16 with caps.
I also confirmed the other numbers:
3428 DSL. Need 8 with caps.
and 3415 need (4) with caps.

Thank you! Knowing the depth of that bottom shoe is very helpful. I'm afraid I still need the weight of each sash, though. The stamps printed on a balance indicate the strength calibration of the spring; in other words, it indicates how much weight they can support. However I've never seen your stamps before and I have no idea if one of our more standard stamps can work. In order to confirm, I will need to know the exact weight of the sash supported by each different balance you have. In the meantime, see our Series 395 channel balance. I'm confident this is the balance you have. We have a chart on each Series 395 store page that shows you how much weight each standard option supports. It's entirely likely our stamp options can work for you, but you need to weigh your sash to confirm. |

I don't know if the Series 395 can work for all of them. I'm only going off of the photos you've shown us. A balance's Series is determined by the nylon attachments on each end of the metal channel. The Series 395 comes with the 19-005 top and 15-001 bottom. If these are the same on all of your balances, then yes, the Series 395 will work for all of them. As for the stamps, knowing your window sizes will not be enough. We need to know the exact weight of each sash. You definitely don't want a spring strength that's stronger than the sash weight, either. If a spring is too strong, then the window will drift up after you close it. |
