Hello! I have a channel balance with a stamp ready 33 5 XC CMC 9. Am I correct in assuming the 33 5 portion refers to a 3350 weight option? Or do I need to go weigh the window? Thanks!

Thanks for writing in! Since the stamp is being cross-referenced, with a different stamp rating system, it may be a good idea to confirm the exact weight of the sash.
The 3350 stamp would be one we typically recommend for this stamp but that would depend on the exact replacement balance you need. To determine this, I would need to see the attachment from the top and bottom of the balance as well as the pulley system in the center of the balance where the spring and the string meet.
Please don't hesitate to reach out with any questions you might have.
