Option for 32-12?

Question

I have a 33" sash that matches up to the 385 replacement.  My stamping is "32-12 GB5 CMC (32HP39-41 )"  What option should I use?

Thanks for posting your question. For the S385-33 channel balance, you would go with the 3270 option based on your stamping of"32-12" which holds a sash weight of 39-42 pounds. Being as that is a very heavy spring, I encourage you to weigh your sash on a scale to confirm that your sash weight falls within that range. Make sure to let us know how you made out.
