Thanks for your patience while we look into this. You have a very old style balance that is unfortunately not made anymore. The good news is that we can still supply an adequate replacement by using different parts assembled together as a custom order.

To be more specific, we would use our plain channel Series 770 but with the bottom clip swapped out for our 15-036 double hook. Does that look good to you?

Before we go any further, I'll need a few pieces of information from you. To start, can you tell me the exact weight of the sash, down to the ounce? Our new balances have a somewhat different calibration compared to the old style so we need to recalculate how much tension to give the spring. Knowing the sash weight would allow us to do that.

Can you also tell me how many balances you needed altogether?

Thank you for your patience. The sash weighs 8lbs 15 ounces. I would like to replace all the balances at once for both my windows, so I'd like to purchase 4 balances.

Great, thank you! In that case, we can use the 28A stamp option. Two units working together can carry 7 through 12 pounds, so that should be perfect for your sash weight.

I'll go ahead and email you a custom purchase link and price quote now. This will allow you to add these assemblies to your cart so that you can checkout as normal.

To reiterate from the top, we're using an S770-28 channel balance with a 28A stamp and with the bottom clip swapped out for our 15-036 double hook. We believe this will work as a suitable alternative to your old, discontinued assembly.

Please feel free to reach out if you had any questions!
