Thanks for posting! There is, in fact, a winged version of the 19-002. Please see our 19-005. If you have the 19-005, then I do not think that the S350-21 is the replacement that you need. You should look through our Non-Tilt Channel Balance Section and see if you can find a Series that matches yours.
Without having your old channel balances on hand, it's really hard for me to say what will act as a replacement Your best bet is to see if there's an identical window in the house that may have the same balances. As for the length of your channel, it's actually better to base it off the height of the glass, not the entire sash. What is the height of the glass for that window? |

Thanks for getting back to us. I agree, 19" is what I would choose, as well.
Now, once you've identified your Series, all you have left are the stamps. These determine how heavy a sash your balances can support while working in tandem. The weight ranges for a 19" non tilt channel balance are as follows: 1810: 5 through 8 pounds 1820: 8 through 12 pounds 1830: 12 through 14 pounds. 1840: 14 through 17 pounds. Please keep in mind that the weight range information is based on 2 balances per sash. Balances are designed assuming friction in the jamb weather-strip will carry a portion of the sash weight. Suggested sash weights are approximate. |
