Thank you for contacting us! I'm afraid I can't identify your balance from these photos alone. The top fitting is a very important detail but it isn't shown here. May we see photos of yours? We'd also like you to measure the bottom fitting as shown below. It looks like yours may be damaged so you'll want to measure an undamaged version for an accurate size.

6 Sept 2023 Dear Emily, I appreciate your concern. One window has a balance marked 2830 BSI AT that needs 2 rods, and another stamped 3430 BSI AT that measure 1/2" wide. The top looks like your 19-004 with wings in the spring/back side and the bottom looks like either 15-001 or 15-002, but I don't see extensions rearward, but they may have broken off.
I was unable to download my other pictures, so maybe you have an email address that I can send them to. I am on the road and will return home to measure this piece on 16 September, so no big rush and I will keep your email and measure it then. Thanks Daryl

Thanks for getting back to me! Based on what I see in these new photos, I'd agree the Series 370 channel balance is what you want as long as the bottom fitting is non-winged and measures 1" deep. I also recommend the 3430 option for the 3430 stamped balance and the 2830 option for the 2830 stamped balance. Pricing can be found on the S370-35 and S370-29 store pages as well! |
