This is for an old Sunair window.  It has a number 1520 on one side, not sure if it is a part number. 17.25 in inches in length.

Thanks for posting. Can you double-check the length of the metal channel? Please be sure not to include the nylon fittings in this measurement. If it's 16", see our S350-16. You'll need a stamp option of 1520.
