Would you please help me determine the correct channel balance for my application?
It is a 9/16" (1/2") steel channel. The steel channel measures 34 inches in length. the numbers stamped on the channel are 33 16L. Pictures attached.
Thanks.

I'm afraid I can't say for sure what would match based just on this picture. Can you show me the bottom shoe, as well? Finally, show us the clip at the end of the cord. Thanks!

Thanks! See our S390-34, I think this may be what you want. I'm not sure about the stamp option. I would weigh your sash to see if any option on the S390-34 store page is a match. If your sash weight is not represented, let me know!
