Thanks for contacting us. We can replace this balance but it will have to be a special order due to its configuration. Specifically, you have a 19-041 top nylon fitting and a 15-005 bottom nylon fitting. Does that look good to you?

If so, please tell me the length of the metal channel, the number printed on it, and the quantity you need. Once I have this information, I'll email you an order link and price quote for the requested quantity.

CMO 2. I will need 8 balancers

Thanks! I'll need you to clarify what that stamp reads. It's important that this we're accurate, since custom balances cannot be returned for a refund. If you cannot read the stamp, then we'll need the exact weight of the sash instead. Please be as precise as possible.

Why can't I ups you the old unit as to avoid mistakes?

If the stamp is unreadable then that won't really help us. There's no way for us to determine the spring calibration just by having the balance in hand. The only other way to determine that, aside from the stamp, is to get the weight of the sash.

You can send it to us if you want, but if the stamp is unreadable then we won't be able to do anything with it. If the stamp is readable, then you can just take a picture of it or tell us what it says.

Thanks, Jim! That definitely looks like "28-9" to me. I was afraid of this. We can still help, but stamps ending in "9" or "90" use an old rating system that is no longer standard in the industry. One of our options may work anyway, but I'll definitely need the exact weight of the sash. That way we can calculate what the proper spring strength rating will be.

Once I know that, I'll email you an order link and price quote for 8 of these.

Unfortunately I'm in NJ and the sash is in Florida. I'll have to call you next time I go down.
