Thanks for posting. This looks similar to an S795-20. You'll need a version of the old T-Lock Shoe to confirm whether you can use the one that comes by default with these balances (or 15-195 1-1/4" Closed Cam T-Lock Shoe), or if you need to swap it out with the 15-195B or 15-194, sold separately, instead. Also confirm that this balance attaches to the top of the window track with a screw-on tab. Let me know if you have any other questions.
Is there an identical window in the house that still has balances with the shoes intact? If so, could you show them to us? As far as your other hardware, the old sash lock is no longer made, but you should be able to replace it with our 90-313, which you can install with screws like our 30-011. As far as the other piece embedded in the frame, I am not certain what it is. Is it a vent latch, or a weep hole cover? Let us know and we'll go from there. Many thanks.
Hey, thanks for getting back to me. While I hate not being able to narrow it down further, I do think it's probably best to buy the S795-20, along with two extra shoes, the 15-194 and 15-195B (the 15-195 comes by default with the Series 795). I'll post a video below that shows how to swap out the shoes. To be honest, my suspicion is the 15-195 is what you need based on your measurements, but it's always best to confirm. Fair enough on the vent cover. Let me know if you have any other questions, and many thanks for your business, we really do appreciate in these times.
Looks like you need new pivot bars. I'm afraid I can't really say what pivot bars you need looking at fragments alone, but two commonly used with the Series 795 are the 26-021 and 26-366. Look these over and see if you think one of these might be what you need.
