Channel Balancers
Thanks for reaching out to us. I'm not sure why the balance might have come out, especially if nothing is damaged. Have you tried reinstalling it yet?
If you just wanted to pursue a new replacement, then I'd be happy to help you. However I need clearer photos of the balance itself. I specifically need to see the top end, bottom end, the hook at the end of the cord, and the stamp. Please let me know if that's possible.
That is peculiar. I don't see any damage here, or any reason why these might have fallen out.
What I can tell you is that they appear to be a match for our Series 395. This comes with a 19-005 top and 15-001 bottom nylon fitting, which appear to match your original design quite well.
But there's no telling whether replacement is even necessary. You may just want to try reinstalling it to see if it still functions. Just make sure to monitor it closely in case it suffers the same failure.
You can see a full price breakdown on the S395-30 store page. Shipping cost will depend entirely on what shipping method you choose during checkout, but this is calculated for you automatically during that process.
