Perfect. I think I have an idea, though it would have to be custom made. I'm thinking of using our S750-24 channel balance, but attaching our 15-159 shoe at the bottom. We would also be using the 23R stamp option; a pair of balances with this option can carry a window sash weight of 10 through 18 pounds. Finally, your top and bottom sash will require two different S clips at the top in order to install; the top sash will need the 19-029 and the bottom sash will need the 19-030. Please review this hardware and let me know if you think this will work in your jamb.
If so, we'll email you a custom order link for your review. Let us know if you have any questions!
Hi, Mike! Thanks for the detailed information. Hopefully we can help.
These are estimations from the dimensions you gave. You should compare them to the ones you have in the existing windows just to be 100% sure.
For the 34-7/8" x 19-1/2" window, I recommend eight S750-20 balances with a stamp of 19HD, which can support sashes weighing 17 through 22 pounds.
For the 24-7/8" x 23-1/2" window, you will need four S750-24 balances with a stamp of 23HD, which can support 18 through 22 pounds.
We would specially attach the 15-159 shoe to each of the above window balances. I also recommend ordering six of the 19-029 and six of the 19-030.
Please look over this information and let me know what you think. If it looks good to you, let me know and I'll email a special order link for the above balances.
Hi there, I'm afraid we don't sell jambs, just balances to install into them. Sorry for the inconvenience.
You can absolutely buy these parts separately and assemble it yourself, yes. Just note that any balance altered in this way cannot be returned for a refund. Custom made balances are also non-refundable, though, so in that aspect there isn't much difference.
I'm also required by policy to tell you to make sure to wear safety glasses and goggles before you attempt any alterations like you have in mind. These cords are under a lot of tension and if they slip out of your grip, that plastic could shatter. I've seen people I've worked with get hit in the eye in such circumstances, so take all necessary precautions. You definitely want to use a bench vice to keep that cord secure before you try swapping anything out.
A lot of older window jamb liners are only held in place by the pressure provided by the sash itself. Once the sash is removed, they can be taken out by hand.
Of course, depending on how old it is, that's easier said than done. Age and sun exposure can make the vinyl much more brittle than it was when it was originally installed. With that in mind, you have to be extra careful not to crack it during removal. One trick I've seen is putting soapy water on the sill at the bottom of the jamb liner to help lubricate its removal. You could try that and see how it goes.
