ID springs and clips for windows
Thanks for reaching out to us. Looks like the bottom fitting on your balance, indicated in Slide 3, is fairly large compared to most shoes found on our balances. I think we can still help, but it will have to be a custom order.
To go into detail, I'm thinking of using a 17" long metal channel with a 1630 stamp option. This stamp carries 12 through 14 pounds and is the same rating as your old 16C, so I think it's the best option.
I'll then attach our 19-002 top and 15-003 bottom nylon fitting to either end. What I want you to do now is review the specs we show for these components and verify that they match. If it looks good, let me know how many you wanted to buy and we can get the ball rolling on a custom order.
As for the top sash guide, I think our 18-199 is going to be our closest option. This is also very different, though, so you should also check these dimensions to be safe.
