Hello,
I have ordered these from you in the past. I have two more windows, besides this one, to order. I hoping that once I know the type of spring I can figure out the size by the label. What does 20 4 HQ mean? If I know that, hopefully I will not need to send you more pictures.

Hi Anne, thanks for writing in. The stamp that you indicate tells us the necessary spring strength. In order to determine the correct series, we need to see both of the plastic attachments at either end of the metal channel.
