296 fx cmc 11 window spring

Question

The plastic ends on my guide looks a little different from the ones y'all have and wanted to make sure it fit. The metal channel is 30 inches.  The plastic base also is exactly an inch wide if that helps. no major stamping other than the printed numbers in the pictures.

Thanks for posting. It looks like you have the S380-30 or S385-30 Channel Balance. The only difference between these two balances is the shoe depth. See below. For a stamp option choose 2960.
