21" 5/8" Channel Block & Tackle Window Balance

Question

I need a replacement for a 21" 5/8" Channel Block & Tackle Window Balance.

The stamped Code is 2030 F.

I am attaching photos of the 2 nylon endpieces, the hook and the block & tackle/spring set.

Do you have a replacement for this and, if so, can you provide a price?

I need 4 pieces.

Thank you,

Neil

Thanks for writing in! Your balances appear to be the Series 350 Channel Balance. Specifically, you'll need the S350-21 with a 2030 stamp.

Please let me know if there is anything else I might be able to assist with.
