S380-29 Option

Question

From the detailed information on your website, I have determined that I need to order two S380-29 Channel Balances. However, I need help choosing the correct option. There is no stamp on the broken Channel Balance but the following code is printed on the metal: 28 4 FX CMC 11

I have removed the window and weighed it - it is 25 pounds.

Thanks!!

Thanks for contacting us! I'd recommend the 2840 option. This can support a window sash weight range of 23 through 28 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.
