The length of the inner components is irrelevant. All that matters is the length of the balance, the stamp code on the metal channel, and the attachments at either end of the balance. Without seeing pictures I can't at all confirm what you have, but if it's a 23-1/4" metal channel with the 16-027 attachment, and the window weighs less than 19 lbs, then an S745-23 with a stamp option of 22.25-3, for a window sash that weighs 13 through 19 lbs, is logical. |
