metal part is 28 inches long and with plastic ends it's 25 inches long.
What channel balance do you suggest?

Thank you for sharing your photos with us, Susan. Your balance looks close to both our S380-28 and S385-28. The difference between these two balances lie within the bottom balance shoe. For the Series 380, the bottom balance shoe measures 1" in depth. As for the Series 385, the bottom shoe measures 1-3/32" in depth. You will need to measure the depth of your shoe, like the diagram below to confirm which balance will be the better match. In your stamping, I am actually seeing "2730". But if it says, 2790 as you mentioned, none our tamp options match up to your weight system. Therefore, you will need to weigh your sash on a bathroom scale and refer to the sash weight chart on the product page. There, you will determine which stamping works best based on your sash weight.

I hope this has answered all of your questions. Please let us know if we can be of any further help. |

Thanks for replying back. Seeing a clearer up close photo of the stamped number, I am able to see the "9" now. My apologies for the confusion. As for weighing the sash, you want to weight the part that can be removed from the window (so basically the part that you pull and push down that opens and closes the window). Once you remove it, you can place it on any bathroom scale. From there, refer to the sash weight chart on the product page to determine the most appropriate option to go with. |

Ok. So you want to go with the stamping that accommodates that sash weight. Look below at the sash weight chart to decide on the most appropriate stamp option. Stamp Option Sash Weight Range 2710 5 to 9 lbs 2720 9 to 13 lbs 2730 13 to 19 lbs 2740 19 to 26 lbs 2750 26 to 30 lbs 2760 30 to 33 lbs 2765 33 to 36 lbs 2770 36 to 39 lbs |
I would say my window balances match 28" series 380 and the sash weight matches 2750.
What would be the order number of the window balances I should get?
thank you for all your help!
