Hello I'm ordering new Channel balances and the number stamped on the balance is 27 4 10 Caldwell.
Does that mean 2710 on the sash weight?

Thanks for the help

Hey, George. I'm not sure. I wouldn't necessarily disregard that 4. I think you might have a sash weight of 2740, but you should weigh your sash just to be certain. That's always better than guessing!
