Hi. This piece is used to cover the top of the spring of a Kolbe double hung window. I think it also prevents the window from being opened all the way to the top. Can you tell me if you have this item? I have 20 windows and they have all cracked due to age.

Thanks for reaching out! The part you are searching for is a sash stop use to prevent the sash from traveling up into the window too far. This stop reminds me of the 55-110 Sash Stop. You'll need to carefully look over the dimensions to confirm that this is the correct replacement for your repairs.
