Replacement balance shoe
I'm afraid that the company who made your shoe has gone out of business. The only solution we can recommend is replacing the balance entirely. We recommend our Series 795. You will need the length of the metal channel and stamp to determine what size would be best.
Keep in mind the Series 795 comes with a 1-1/4" wide bottom shoe and installs at the top using a screw. If yours is different, it's important to let me know before you buy anything.
Hello again! Yeah, I've seen balances installed backwards like that from time to time. That is to say, with the spring, pulley, and guts facing out. I'll be honest with you, I have no idea why some older balances are installed this way. I don't know the benefit and I don't know if installing them the other, more common way will cause any issues. I've only ever seen that kind of setup through customers submitting their images here, I've never worked on them with my own two hands. That said, I've also never heard any complaints when I recommend our balances. I feel like it's safe to say they'll work if you install them with the guts facing in.
That aside, we can specially make this balance with a hook on top. That'd be our 15-198. Before I send you a special order link, can you tell me the stamp number printed on your balance? Can you also tell me how many you need?
Great! That's just what we need to see. As for quantity, we do recommend replacing both balances at the same time. It will make sure they last longer, since the new balance won't have to pick up the slack for the old balance. I'll email you a custom order link right now.
We're glad that we were able to help fix your window and we'll be here if you have any future hardware questions about your other windows. Thank you!
