Requesting help identifying part

A home owner from Southern California says:
Could you help me find the replacement part for my window balance. I have a double hung window, non-tilt, 1/2" channel width, the length of the metal portion is 34 inches, and the photos show the ends.

Thanks for posting. Check out our S385-34 channel balance and let me know if this is a good match for you. Based on your stamp, I would also recommend our 3340 option.
