Thank you for reaching out to SWISCO. So I see you are showing us a number of things in your photos. I see a vent latch, a tilt latch, and a balance. We can help you with all of those parts. If you are just focused on getting the balance replaced, we will need to see some up close detailed photos of the entire balance, showing any nylon attachments that it may include. Next, please provide us with the metal length measurement of the balance. We can not tell the length from the measuring tape. If there should happen to be any stampings or markings on the balance, please make sure to provide us with that information as well.
Thanks for the added photos. Just to clarify, the individual components of the balance are not sold separately, and you will have to replace the entire balance. I think we can help you do this, but we'll need a little more information to be able to help. Can you show us the entire balance, preferably an undamaged version, removed from the window? Can you show us another picture of the bottom attachment, and an you show us how the top of the balance connects to the window--is it screwed in or is there a hook at the end of the cord? Could you also show us the view of the metal channel's end profile? This should help us identify what you need.
Thanks for the added photos. This looks like a S795-35 Channel Balance. This comes built-in with a 15-195 T-Lock Shoe, which is 1-1/4" wide and Closed Cam. Confirm your T-Lock shoe matches these specifications; if not, you may need to swap out the default shoe with the 15-194 1" shoe or the 15-195B 1-1/4" Open Cam shoe. See the video below for details.
Your stamp code of 34 7 is a little unusual for this type of balance. Could you obtain the weight of your window sash? You should be able to match that precise weight with one of the weight ranges listed with each stamp option on the product page. If your sash weight happens to fall outside these ranges, let us know and we will work something out for you.
OK, thanks for the sash weight. Again, it looks like you need the S795-35. It's good we checked the sash weight, because 32.5 lbs fell outside the weight ranges listed for this balance's existing stamp options. To solve this, we have gone ahead and added a new stamp option to the S795-35 product page, 35E, specifically to support your window sash's weight range. However, because it's a new item, keep in mind that it's going to take 6 weeks for us to have these made up for you.
Again, you'll want to double-check to confirm your balance's T-Lock shoe matches the default one installed on the S795-35 (the 15-195). If not, you may need to swap it out with a different shoe. See my previous post for details. Let us know if you have any further questions.
By product page, I mean the page for the S795-35. Click on the link, scroll down and you'll see a chart that lists weight ranges alongside each stamp option. The stamp options have nothing to do with the t-lock shoe. They indicate the strength of the spring inside the balance. It's crucial that the spring is calibrated precisely to fit the weight range your window sash falls into--you don't want it to be too strong, or too weak. Based on the sash weight you helpfully provided of 32.5 lbs, you will need to select a stamp option of 35E, which we have created to account for your heavier window sash.
The T-Lock shoes purely have to do with how the balance sits inside your jamb track, as well as the size of the pivot bar they accept. They pivot bar is the metal pin that connects the window sash to the shoe, allowing for the window to tilt. If you have an open cam, 1-1/4" T-Lock shoe, our 15-195B, then you will need to swap out the shoe that comes with the S795-35 with the 15-195B. See the video earlier in the discussion for details.
The S795-35 is certainly correct. If you can see 'through' the cam of your T-Lock Shoe; if it has no 'back', then you need a 15-195B 1-1/4" Open Cam T-Lock Shoe. If not, the 15-195 that comes installed with the Series 795 is fine.
