Help identifying sash balance

A handy person from New Jersey says:
First off... I think this service is fantastic! I read all the posts and didn't find my sash balance. These are my numbers, what is the replacement?


02 L9 1327 7-87

I'm curious by nature and was wondering what the numbers mean?
Thank you,

Thanks for posting! We actually don't currently have this balance as it is not a popular size, but I'd be happy to bring in the left and right hand version of this balance for you, since it's a good idea to replace both. I'll post here again as soon as I have something for you to look at!

Alright, Tim, take a look at our new 24-R13-927 and 24-L9-1327. I believe these are the appropriate replacements for your hardware.
