need to identify window balance

Thanks for contacting us. I recognize this balance, however the company that made it discontinued it. This exact assembly is no longer available, but we do have a possible substitute. The only problem is, it will have to be custom made.

The balance I have in mind for you is our S795-33 channel balance, but with a special 15-198 hook attached to the top. The "T" shoe that comes with the S795-33 eliminates the need for the old pivot shoe your balance used, in addition to being easier to install.

If you want to go this route, I will need to know the number printed on your current balance and the quantity you wish to order. From there, we can send you a custom order form and price quote.

Sure, I'm just a little confused. You requested a few different configurations and I'm not sure exactly what it is you want. Based on your last response, I will send you a custom balance order form for two S795-33 balances with a 33E option and a 15-198 clip attached to the top.

Hmm, that's definitely an "E." I'm surprised that it's not strong enough. Did you ever find your old 33E balances to be too weak?

34.6 pounds is a little over what the 33E should typically support. That is usually meant for sashes weighing 30 through 34 pounds. At 34.6, maybe 33F would be better, though I worry that would be too strong since your old balances were 33E. A balance marked with 33F can carry 34 through 37 pounds. Would that work? Were your old 33E balances too weak to begin with?

Sure thing, I'll shoot you an order for that right now. Keep an eye on your inbox.

I would not recommend mixing and matching spring strengths. What would happen then is that the stronger balance would have to work extra hard to make up for the weaker balance, and will end up wearing out faster. There's also a good chance that the sash will end up being unbalanced, of course.
