Balancers for 35LB sash

Hey, thanks for posting. We don't have any 27" channel balances that can support 35 pounds. Can you confirm that weight? If that's correct, it will have to be custom made.

Before we begin on that, though, I need to figure out what Series you have. I've narrowed this down to two possible channel balance Series: either our Series 380 or our Series 385 balances.

Now, as you can see, there is only one difference between these two Series, and that is their bottom shoe. The Series 380 uses the 15-005 while the Series 385 uses the 15-004. I can't quite tell what you have based on your pictures, though. Please carefully compare their dimensions to your own hardware and see which is a better match.

Aha... I see. I missed that. These windows are weird and very uncommon. Although, coincidentally, we had another customer just recently who had the same kind of set up, so maybe they're not as rare as all that. Regardless, we have a couple ideas.

Now, we do have a balance that can support 35 pounds using just a pair, rather than four. However, it would have to be custom made. Plus, I can't really guarantee that it will work for your weird window. It may be worth a shot though. If the springs can support the sash, then I can't really think of a reason why it wouldn't work. It just wouldn't be ideal.

Now, custom made balances cannot be returned for a refund, so let me know if you want to go that route. If so, I will need you to confirm what Series you have and we can work from there.
