Hello! Thanks for your patience during this busy season. We can absolutely supply this balance but it will have to be custom made in our shop since it's not a stock configuration. Basically, it would be our normal S751-33 but with the default bottom shoe swapped out for our special 15-233, to match your original. Does that look good to you? If so, I just needed one last piece of information before we can pull the trigger on this. Can you tell me the exact weight of the sash that this balance supports, down to the ounce? Your stamp is very peculiar for this balance archetype so we will have to calculate your spring calibration from scratch. Knowing the sash weight will allow us to do that. As for replacement, jamb spreaders won't be necessary. I actually don't even think they'll work on this kind of window without damaging the vinyl. You will need to remove the jamb liner entirely and slide the balance and shoe in from the end of the track. The video below will show you what I mean. |

Hello again, Leo. Looking over this information, I think the following configurations will be ideal for these balances:
The stamps are a little different but they hold the same weight, so you should be okay. What I'll do now is email you a purchase link and price quote for both sizes that will allow you to add 8 each to your cart. that way you can checkout as normal. |
