S-377 Series Window Balance

A handy person from Florida says:
I have a old balance that the metal channel measures 18.5", can these be ordered.
The problem is the 1820's I ordered are to long and hit at the bottom and the 1720's I ordered do work but are not a exact replacement for the originals. Any suggestions.

We can make balances whose lengths end on 1/2", but it will have to be a special order. Can you just tell me how many you need? Can you also tell me what your original stamp reads? Once I know that, I'll email you an order link and price quote for the desired quantity.

A handy person from Florida says:
The original stamp is 1820, I will always order about 20 of them at a time.

Thanks for getting back to us! Would it be possible to see a photo of the nylon fittings on either end of your balance? A thought occurred to me that you might have a special kind of balance with a particular design. It's similar to our Series 377, but different enough to be incompatible. I just want to be 100% sure; custom balances cannot be returned for a refund so I want to eliminate any doubt. Hopefully that makes sense.

Here is a pic, on the left is the old balance, Swisco new one is on the right.

Thank you. I don't see the top nylon fitting, but I will take your word that it's the 19-018. That shoe does not match the special one I had in mind so we can cross that off the list. Thanks again for confirming for me!

I'll email you an order link and price quote right now for 20 of these balances. Just keep in mind that custom orders cannot be returned for a refund. If there is any doubt in your mind that your balance doesn't have the 19-018 top and 15-005 bottom nylon fittings, tell me now.
