Window stop replacement?

Question

Hi, I have a double hung window. The brand is Mastic. On the upper sash, there is what I call a "window stop" to prevent the lower window from being opened past this stop. A few windows are missing them. Is this a part that Swisco sells?

Hey there!

Thanks for reaching out to us. The sash stop shown here reminds me of the 26-338, 26-106, and 26-107. We can't be sure if any of them are what you need since your part is installed, however. Review the specifications and see how they compare with yours.
