795 balance, except two differences

My balances seem very similar to your 795 with the exception of a groove in the bottom of the channel and a hook on top as depicted in the attached pictures.

I have many wiondows and my balances are primarily 33D and 25C.

Hope you can help with my unusual balances.

Thank you,
Charles

Thanks for posting, Charles. This is a special kind of balance that will need to be custom made. They don't make these with a groove anymore, but that won't be necessary. The biggest difference is the hook on top. Can you just tell me how many of each you need?

The length of the metal channel of the 33D is exactly 33 inches.
The length of the metal channel of the 25C is exactly 25 inches.

Without the groove, I don't know hat they will work with my pivot bars.

I would need 2 33D's to test.

Sure, I'll email you a custom order form for two of those right now.

Hi, I made the purchase but I was wondering how these would work without the groove for the pivot bar. Could you briefly explain why the groove isn't necessary?

Thanks

The way the balances are designed, the pivot bars actually come out just by twisting the sash upon removal. I've replaced this type of balance countless times and it works just fine without the groove. That's the main reason why the manufacturer phased this style out, as they also felt it was unnecessary.

Thank you. I received the balances and I was able to install them without difficulty as you predicted.

When I unlock the window with the new balances, the window now flies halfway up to the top. Is this normal behavior for new balances or are they overpowered for my window and should I have 33C's instead of 33D's?

I'm asking because I have other balances to order. If it is normal behavior and the springs just need time to fatigue and weaken, then I need to custom order 2 25C's with hooks or if overpowered, I need to order 25B's with hooks.

Thank you.

Ah, I'm sorry you're having trouble. It definitely sounds like the springs are overpowered. Did you have this problem with your old balances? If your old balances worked fine with the 33D stamp, then the new ones should be fine, as well. Can you also tell me the exact weight of the sash?

No, but the problem seems to have resolved itself. Maybe the springs needed to fatigue, but the window no longer lifts on its own. Can I order 2 25C's with the hook mechanism, please?
