Hi,

I believe these were on our Scherer Brothers Windows here in Minnesota. It just says Truth Hardware on it with no number. These are plastic and cover the mechanism that opens and closes the windows. Thanks for any help you can give me.

Hello,

Could you show us the operator that this cover installs on, including the arms that move the window sash in and out? Thank you!

Great, we're almost there. Now I just need to see a photo with the window open so that the arms that move the sash are visible. Thank you.

Perfect, thanks! This looks like either a 39-032 or 39-156. The difference between these two operators is in the length of the link arms, so compare all the dimensions we list in the pictures on each shop page with each of your operators to ensure you're getting the right replacement. For a new cover and T handle, see the 39-107 and 39-102. Thank you!
