Snap in glazing
Hello, thanks for posting! Take a look at our 55-076. Compare its dimensions to yours to see if this could be a match
Would you be able to show us your channel balance? We would also like to know the stamp or imprint on the metal channel. This will help us determine if you have the appropriate spring strength. We unfortunately do not carry replacement glass panels - you may want to contact your local hardware store.
Thanks for the follow up pictures. The difference between the Series 380 and the Series 385 lies in the depth of the shoe. Take a look at the picture below for more detail. You will need to determine this dimension to select the appropriate balance.
A 2740 stamp indicates a sash weight range between 19 to 26 pounds. I recommend getting your exact sash weight to ensure you have the appropriate balance. Finally, in regards to your top sash guide, as long as the dimensions are the same I think the 18-061 looks like a good match!
