Series 751 Channel Balances that are 30-5/8" long?

Question

Looking at matching the balancer out of my JeldWen window. It looks almost identical to your 751 ribbed balancer and has a marking of 28HB and 3.S.I on the balancer. Thought that was your nomenclature but must not be since the unit is 30-5/8" long. I initially thought that would equate to your 28HD but mine is 30-5/8" and your 28HD is 29" long. What would I order from Swisco. The lock shoe is black. Thanks - Brian

Thanks for posting! I see what you mean, that is weird. I'm not sure why a balance at 30-5/8" long would have a 28HD stamp. That said, we should be able to custom make something for you that will work. We can special make a 30-5/8" length just for you. Before we can begin, though, I'd like to know the weight of the sash so we can calculate the proper strength of the spring. I don't think we should go by the old stamp, since it's so different. Can you also tell me how many you need?
