Channel balances "32 3 CS CALDWELL"

A home owner from san diego, ca says:
Can you provide a price for (2) identical channel balances, marked "32 3 CS CALDWELL"? Images of top, bottom, pulley hook, marking, and the stamp impressed in a matching channel balance (that still works)

Thanks for posting! Before we can provide an applicable substitute for your balance, what is the length of your metal channel in inches? Make sure not measure the attachments as well, we just need the length of the channel.
A home owner from San Diego says:

Thanks for the prompt response. Curiously, the (broken) channel-only length is 32 5/8", and the functional channel from the same window is 33 1/8".

The sash weighs 20#.

I see. Most channel balances have an even length. It's possible that this is why the shorter balance broke. Either way, I recommend that you take a look at our S385-33 with a 3230 stamp option.
